+Description:
+ Specifies the hysteresis of threshold that the device is comparing
+ against for the events enabled by
+ <type>Y[_name]_thresh[_(rising|falling)]_hysteresis.
+ If separate attributes exist for the two directions, but
+ direction is not specified for this attribute, then a single
+ hysteresis value applies to both directions.
+ For falling events the hysteresis is added to the _value attribute for
+ this event to get the upper threshold for when the event goes back to
+ normal, for rising events the hysteresis is subtracted from the _value
+ attribute. E.g. if in_voltage0_raw_thresh_rising_value is set to 1200
+ and in_voltage0_raw_thresh_rising_hysteresis is set to 50. The event
+ will get activated once in_voltage0_raw goes above 1200 and will become
+ deactived again once the value falls below 1150.

- interrupts: Should contain the IRQ line for the ADC
- atmel,adc-channels-used: Bitmask of the channels muxed and enable for this
device
- - atmel,adc-num-channels: Number of channels available in the ADC
- atmel,adc-startup-time: Startup Time of the ADC in microseconds as
defined in the datasheet
- atmel,adc-vref: Reference voltage in millivolts for the conversions
resolution will be used.
- atmel,adc-sleep-mode: Boolean to enable sleep mode when no conversion
- atmel,adc-sample-hold-time: Sample and Hold Time in microseconds
+ - atmel,adc-ts-wires: Number of touch screen wires. Should be 4 or 5. If this
+ value is set, then adc driver will enable touch screen
+ support.
+ NOTE: when adc touch screen enabled, the adc hardware trigger will be
+ disabled. Since touch screen will occupied the trigger register.
+ - atmel,adc-ts-pressure-threshold: a pressure threshold for touchscreen. It
+ make touch detect more precision.

+ *
+ * Read-only raw channels:
+ * - illiminance_clear [lux]
+ * - illiminance_ir
+ * - proximity
+ *
+ * Triggered buffer:
+ * - illiminance_clear
+ * - illiminance_ir
+ * - proximity
+ *
+ * Events:
+ * - illuminance_clear (rising and falling)
+ * - proximity (rising and falling)
+ * - both falling and rising thresholds for the proximity events
+ * must be set to the values greater than 0.
+ *
+ * The driver supports triggered buffers for all the three
+ * channels as well as high and low threshold events for the
+ * illuminance_clear and proxmimity channels. Triggers
+ * can be enabled simultaneously with both illuminance_clear
+ * events. Proximity events cannot be enabled simultaneously
+ * with any triggers or illuminance events. Enabling/disabling
+ * one of the proximity events automatically enables/disables

-Driver: comedi_parport
-Description: Standard PC parallel port
-Author: ds
-Status: works in immediate mode
-Devices: [standard] parallel port (comedi_parport)
-Updated: Tue, 30 Apr 2002 21:11:45 -0700
-
-A cheap and easy way to get a few more digital I/O lines. Steal
-additional parallel ports from old computers or your neighbors'
-computers.
-
-Option list:
- 0: I/O port base for the parallel port.
- 1: IRQ
-
-Parallel Port Lines:
-
-pin subdev chan aka
---- ------ ---- ---
-1 2 0 strobe
-2 0 0 data 0
-3 0 1 data 1
-4 0 2 data 2
-5 0 3 data 3
-6 0 4 data 4
-7 0 5 data 5
-8 0 6 data 6
-9 0 7 data 7
-10 1 3 acknowledge
-11 1 4 busy
-12 1 2 output
-13 1 1 printer selected
-14 2 1 auto LF
-15 1 0 error
-16 2 2 init
-17 2 3 select printer
-18-25 ground
-
-Notes:
-
-Subdevices 0 is digital I/O, subdevice 1 is digital input, and
-subdevice 2 is digital output. Unlike other Comedi devices,
-subdevice 0 defaults to output.
-
-Pins 13 and 14 are inverted once by Comedi and once by the
-hardware, thus cancelling the effect.
-
-Pin 1 is a strobe, thus acts like one. There's no way in software
-to change this, at least on a standard parallel port.
-
-Subdevice 3 pretends to be a digital input subdevice, but it always
-returns 0 when read. However, if you run a command with
-scan_begin_src=TRIG_EXT, it uses pin 10 as a external triggering
-pin, which can be used to wake up tasks.

+ * Driver: comedi_parport
+ * Description: Standard PC parallel port
+ * Author: ds
+ * Status: works in immediate mode
+ * Devices: (standard) parallel port [comedi_parport]
+ * Updated: Tue, 30 Apr 2002 21:11:45 -0700
+ *
+ * A cheap and easy way to get a few more digital I/O lines. Steal
+ * additional parallel ports from old computers or your neighbors'
+ * computers.
+ *
+ * Option list:
+ * 0: I/O port base for the parallel port.
+ * 1: IRQ (optional)
+ *
+ * Parallel Port Lines:
+ *
+ * pin subdev chan type name
+ * ----- ------ ---- ---- --------------
+ * 1 2 0 DO strobe
+ * 2 0 0 DIO data 0
+ * 3 0 1 DIO data 1
+ * 4 0 2 DIO data 2
+ * 5 0 3 DIO data 3
+ * 6 0 4 DIO data 4
+ * 7 0 5 DIO data 5
+ * 8 0 6 DIO data 6
+ * 9 0 7 DIO data 7
+ * 10 1 3 DI ack
+ * 11 1 4 DI busy
+ * 12 1 2 DI paper out
+ * 13 1 1 DI select in
+ * 14 2 1 DO auto LF
+ * 15 1 0 DI error
+ * 16 2 2 DO init
+ * 17 2 3 DO select printer
+ * 18-25 ground
+ *
+ * When an IRQ is configured subdevice 3 pretends to be a digital
+ * input subdevice, but it always returns 0 when read. However, if
+ * you run a command with scan_begin_src=TRIG_EXT, it uses pin 10
+ * as a external trigger, which can be used to wake up tasks.

-
-*/
/*
- Dave Andruczyk <dave@tech.buffalostate.edu> also wrote a
- driver for the PCL-711. I used a few ideas from his driver
- here. His driver also has more comments, if you are
- interested in understanding how this driver works.
- http://tech.buffalostate.edu/~dave/driver/
-
- The ACL-8112 driver was hacked from the sources of the PCL-711
- driver (the 744 chip used on the 8112 is almost the same as
- the 711b chip, but it has more I/O channels) by
- Janne Jalkanen (jalkanen@cs.hut.fi) and
- Erik Bunn (ebu@cs.hut.fi). Remerged with the PCL-711 driver
- by ds.
-
- [acl-8112]
- This driver supports both TRIGNOW and TRIGCLK,
- but does not yet support DMA transfers. It also supports
- both high (HG) and low (DG) versions of the card, though
- the HG version has been untested.

+TODO:
+ - Dan Carpenter would like to see some cleanups to the microframe
+ scheduler code:
+ http://www.mail-archive.com/linux-usb@vger.kernel.org/msg26650.html
+
+ - Should merge the NAK holdoff patch from Raspberry Pi
+ (http://marc.info/?l=linux-usb&m=137625067103833). But as it stands
+ that patch is incomplete, it needs more investigation to see if it
+ can be made to work for non-Raspberry Pi platforms that lack the
+ special FIQ interrupt that the Pi has. Without this patch, the driver
+ has a high interrupt rate (8K/sec).
+
+ - The Raspberry Pi platform needs to have support for its FIQ interrupt
+ added, to get the same level of functionality as the downstream
+ driver. The raspberrypi.org developers have indicated they are
+ willing to help with that.
+
+ - Some of the default driver parameters (see 'struct dwc2_core_params'
+ in core.h) won't work for many platforms. So DT attributes will need
+ to be added for some of these. But that can be done as-needed as new
+ platforms are added.
+
+ - Eventually the driver should be merged with the s3c-hsotg peripheral
+ mode driver, so that both modes of operation can be supported with a
+ single driver. But I think that can wait till after the driver has
+ been moved to mainline.
+
+ - After that, OTG support can be added. I'm not sure how much demand
+ there is for that, though, so I have that as a low priority.
+
+Please send any patches for this driver to Paul Zimmerman <paulz@synopsys.com>
+and Greg Kroah-Hartman <gregkh@linuxfoundation.org>. And please CC linux-usb
+<linux-usb@vger.kernel.org> too.

3) Expand device set. Lots of other maxim adc's have very
similar interfaces.
+MXS LRADC driver:
+This is a classic MFD device as it combines the following subdevices
+ - touchscreen controller (input subsystem related device)
+ - general purpose ADC channels
+ - battery voltage monitor (power subsystem related device)
+ - die temperature monitor (thermal management)
+
+At least the battery voltage and die temperature feature is required in-kernel
+by a driver of the SoC's battery charging unit to avoid any damage to the
+silicon and the battery.

+A New Scripting Dynamic Tracing Tool For Linux
+[www.ktap.org][homepage]
+
+ktap is a new scripting dynamic tracing tool for Linux,
+it uses a scripting language and lets users trace the Linux kernel dynamically.
+ktap is designed to give operational insights with interoperability
+that allows users to tune, troubleshoot and extend kernel and application.
+It's similar with Linux Systemtap and Solaris Dtrace.
+
+ktap have different design principles from Linux mainstream dynamic tracing
+language in that it's based on bytecode, so it doesn't depend upon GCC,
+doesn't require compiling kernel module for each script, safe to use in
+production environment, fulfilling the embedded ecosystem's tracing needs.
+
+More information can be found at [ktap homepage][homepage].
+
+[homepage]: http://www.ktap.org
+
+## Highlights
+
+ * simple but powerful scripting language
+ * register based interpreter (heavily optimized) in Linux kernel
+ * small and lightweight (6KLOC of interpreter)
+ * not depend on gcc for each script running
+ * easy to use in embedded environment without debugging info
+ * support for tracepoint, kprobe, uprobe, function trace, timer, and more
+ * supported in x86, arm, ppc, mips
+ * safety in sandbox
+
+## Building & Running
+
+1. Clone ktap from github
+
+ $ git clone http://github.com/ktap/ktap.git
+
+2. Compiling ktap
+
+ $ cd ktap
+ $ make #generate ktapvm kernel module and ktap binary
+
+3. Load ktapvm kernel module(make sure debugfs mounted)
+
+ $ make load #need to be root or have sudo access
+
+4. Running ktap
+
+ $ ./ktap scripts/helloworld.kp
+
+
+## Examples
+
+1. simplest one-liner command to enable all tracepoints
+
+ ktap -e "trace *:* { print(argevent) }"
+
+2. syscall tracing on target process
+
+ ktap -e "trace syscalls:* { print(argevent) }" -- ls
+
+3. function tracing
+
+ ktap -e "trace ftrace:function { print(argevent) }"
+
+ ktap -e "trace ftrace:function /ip==mutex*/ { print(argevent) }"
+
+4. simple syscall tracing
+
+ trace syscalls:* {
+ print(cpu(), pid(), execname(), argevent)
+ }
+
+5. syscall tracing in histogram style
+
+ s = {}
+
+ trace syscalls:sys_enter_* {
+ s[argname] += 1
+ }
+
+ trace_end {
+ histogram(s)
+ }
+
+6. kprobe tracing
+
+ trace probe:do_sys_open dfd=%di fname=%dx flags=%cx mode=+4($stack) {
+ print("entry:", execname(), argevent)
+ }
+
+ trace probe:do_sys_open%return fd=$retval {
+ print("exit:", execname(), argevent)
+ }
+
+7. uprobe tracing
+

+% The ktap Tutorial
+
+# Introduction
+
+ktap is a new scripting dynamic tracing tool for linux
+
+ktap is a new scripting dynamic tracing tool for Linux,
+it uses a scripting language and lets users trace the Linux kernel dynamically.
+ktap is designed to give operational insights with interoperability
+that allows users to tune, troubleshoot and extend kernel and application.
+It's similar with Linux Systemtap and Solaris Dtrace.
+
+ktap have different design principles from Linux mainstream dynamic tracing
+language in that it's based on bytecode, so it doesn't depend upon GCC,
+doesn't require compiling kernel module for each script, safe to use in
+production environment, fulfilling the embedded ecosystem's tracing needs.
+
+Highlights features:
+
+* simple but powerful scripting language
+* register based interpreter (heavily optimized) in Linux kernel
+* small and lightweight (6KLOC of interpreter)
+* not depend on gcc for each script running
+* easy to use in embedded environment without debugging info
+* support for tracepoint, kprobe, uprobe, function trace, timer, and more
+* supported in x86, arm, ppc, mips
+* safety in sandbox
+
+
+# Getting started
+
+Requirements
+
+* Linux 3.1 or later(Need some kernel patches for kernel earlier than 3.1)
+* CONFIG_EVENT_TRACING enabled
+* CONFIG_PERF_EVENTS enabled
+* CONFIG_DEBUG_FS enabled
+ (make sure debugfs mounted before insmod ktapvm
+ mount debugfs: mount -t debugfs none /sys/kernel/debug/)
+
+Note that those configuration is always enabled in Linux distribution,
+like REHL, Fedora, Ubuntu, etc.
+
+1. Clone ktap from github
+
+ $ git clone http://github.com/ktap/ktap.git
+
+2. Compiling ktap
+
+ $ cd ktap
+ $ make #generate ktapvm kernel module and ktap binary
+
+3. Load ktapvm kernel module(make sure debugfs mounted)
+
+ $ make load #need to be root or have sudo access
+
+4. Running ktap
+
+ $ ./ktap scripts/helloworld.kp
+
+
+# Language basics
+
+## Syntax basics
+
+ktap's syntax is design on the mind of C language syntax friendly,
+to make it easy scripting by kernel developer.
+
+1. Variable declaration
+The biggest syntax differences with C is that ktap is a dynamic typed
+language, so you won't need add any variable type declaration, just
+use the variable.
+
+2. function
+All functions in ktap should use keyword "function" declaration
+
+3. comments
+The comments of ktap is starting from '#', long comments doesn't support now.
+
+4. others
+Don't need place any ';' at the ending of statement in ktap.
+ktap use free syntax style, so you can choose to use the ';' or not.
+
+ktap use nil as NULL, the result of any number operate on nil is nil.
+
+ktap don't have array structure, also don't have any pointer operation.
+
+## Control structures
+
+ktap if/else is same as C language.
+
+There have two method of for-loop in ktap:
+
+ for (i = init, limit, step) { body }
+
+this is same as below in C:
+
+ for (i = init; i < limit; i += step) { body }
+
+The next for-loop method is:
+
+ for (k, v in pairs(t)) { body } # looping all elements of table
+
+Note that ktap don't have "continue" keyword, but C does.
+
+## Date structures
+
+Associative array is heavily used in ktap, it's also called by table.
+
+table declaration:
+
+ t = {}
+
+how to use table:
+
+ t[1] = 1
+ t[1] = "xxx"
+ t["key"] = 10
+ t["key"] = "value"
+
+ for (k, v in pairs(t)) { body } # looping all elements of table
+
+
+# Built in functions and librarys
+
+## Built in functions
+
+**print (...)**
+Receives any number of arguments, and prints their values,
+print is not intended for formatted output, but only as a
+quick way to show a value, typically for debugging.
+For formatted output, use printf.
+
+**printf (fmt, ...)**
+Similar with C printf, use for format string output.
+
+**pairs (t)**
+Returns three values: the next function, the table t, and nil,
+so that the construction
+for (k,v in pairs(t)) { body }
+will iterate over all key-value pairs of table t.
+
+**len (t) /len (s)**
+If the argument is string, return length of string,
+if the argument is table, return counts of table pairs.
+
+**in_interrupt ()**
+checking is context is interrupt context
+
+**exit ()**
+quit ktap executing, similar with exit syscall
+
+**pid ()**
+return current process pid
+
+**execname ()**
+return current process exec name string
+
+**cpu ()**
+return current cpu id
+
+**arch ()**
+return machine architecture, like x86, arm, etc.
+
+**kernel_v ()**
+return Linux kernel version string, like 3.9, etc.
+
+**user_string (addr)**
+Receive userspace address, read string from userspace, return string.
+
+**histogram (t)**
+Receive table, output table histogram to user.
+
+**curr_task_info (offset, fetch_bytes)**
+fetch value in field offset of task_struct structure, argument fetch_bytes
+could be 4 or 8, if fetch_bytes is not given, default is 4.
+
+user may need to get field offset by gdb, for example:
+gdb vmlinux
+(gdb)p &(((struct task_struct *)0).prio)
+
+**print_backtrace ()**
+print current task stack info
+
+
+## Librarys
+
+### Kdebug Library
+
+**kdebug.probe_by_id (event_ids, eventfun)**
+
+This function is underly representation of high level tracing primitive.
+event_ids is the id of all events, it's read from
+/sys/kernel/debug/tracing/events/$SYS/$EVENT/id
+
+for multi-events tracing, the event_ids is concatenation of all id, for example:
+ "2 3 4", seperated by blank space.
+
+The second argument in above examples is a function:
+function eventfun () { action }
+
+
+**kdebug.probe_end (endfunc)**
+
+This function is used for invoking a function when tracing end, it will wait
+until user press CTRL+C to stop tracing, then ktap will call endfunc function,
+user could show tracing results in that function, or do other things.
+
+
+### Timer Library
+
+
+
+# Linux tracing basics
+
+tracepoints, probe, timer
+filters
+above explaintion
+Ring buffer
+
+# Tracing semantics in ktap
+
+## Tracing block
+
+**trace EVENTDEF /FILTER/ { ACTION }**
+
+This is the basic tracing block for ktap, you need to use a specific EVENTDEF
+string, and own event function.
+
+EVENTDEF is compatible with perf(see perf-list), with glob match, for example:
+
+ syscalls:* trace all syscalls events
+ syscalls:sys_enter_* trace all syscalls entry events
+ kmem:* trace all kmem related events
+ sched:* trace all sched related events
+ *:* trace all tracepoints in system.
+
+All events are based on: /sys/kernel/debug/tracing/events/$SYS/$EVENT
+
+**trace_end { ACTION }**
+
+This is based on kdebug.probe_end function.
+
+## Tracing built-in variable
+
+**argevent**
+event object, you can print it by: print(argevent), it will print events
+into human readable string, the result is mostly same as each entry of
+/sys/kernel/debug/tracing/trace
+
+**argname**
+event name, each event have a name associated with it.
+
+**arg1..9**
+get argument 1..9 of event object.
+
+
+## Timer syntax
+
+**tick-Ns { ACTION }**
+**tick-Nsec { ACTION }**
+**tick-Nms { ACTION }**
+**tick-Nmsec { ACTION }**
+**tick-Nus { ACTION }**
+**tick-Nusec { ACTION }**
+
+**profile-Ns { ACTION }**
+**profile-Nsec { ACTION }**
+**profile-Nms { ACTION }**
+**profile-Nmsec { ACTION }**
+**profile-Nus { ACTION }**
+**profile-Nusec { ACTION }**

+# Overhead/Performance
+
+ktap have more fast boot time thant Systemtap(try the helloword script)
+ktap have little memory usage than Systemtap
+and some scripts show that ktap have a little overhead then Systemtap
+(we choosed two scripts to compare, function profile, stack profile.
+this is not means all scripts in Systemtap have big overhead than ktap)
+
+
+# FAQ
+
+**Q: Why use bytecode design?**
+A: Using bytecode would be a clean and lightweight solution,
+ you don't need gcc toolchain to compile every scripts, all you
+ need is a ktapvm kernel modules and userspace tool called ktap.
+ Since its language virtual machine design, it have great portability,
+ suppose you are working at a multi-arch cluster, if you want to run
+ a tracing script on each board, you won't need cross-compile tracing
+ script onto all board, what you really need to do is use ktap tool
+ to run script just in time.
+
+ Bytecode based design also will make executing more safer, than native code
+ generation.
+
+ Reality already showing that SystemTap is not widely used in embedded Linux,
+ caused by problem of SystemTap's architecture design choice, it's a natural
+ design for Redhat and IBM, because Redhat/IBM is focusing on server area,
+ not embedded area.
+
+**Q: What's the differences with SystemTap and Dtrace?**
+A: For SystemTap, the answer is already mentioned at above question,
+ SystemTap use translator design, for trade-off on performance with usability,
+ based on GCC, that's what ktap want to solve.
+
+ For Dtrace, one common design with Dtrace is also use bytecode, so basically
+ Dtrace and ktap is on the same road. There have some projects aim to porting
+ Dtrace from Solaris to Linux, but the process is still on the road, Dtrace
+ is rooted in Solaris, and there have many huge differences between Solaris
+ tracing infrastructure with Linux's.
+
+ Dtrace is based on D language, a language subset of C, it's a restricted
+ language, like without for-looping, for safty use in production system.
+ It seems that Dtrace for Linux only support x86 architecture, not work on
+ powerpc and arm/mips, obviously it's not suit for embedded Linux currently.
+
+ Dtrace use ctf as input for debuginfo handing, compare with vmlinux for
+ SystemTap.
+
+ On the license part, Dtrace is released as CDDL, which is incompatible with
+ GPL(this is why it's impossible to upstream Dtrace into mainline).
+
+**Q: Why use dynamically typed language? but not statically typed language?**
+A: It's hard to say which one is more better than other, dynamically typed
+ language bring efficiency and fast prototype production, but loosing type
+ check at compiling phase, and easy to make mistake in runtime, also it's
+ need many runtime checking, In contrast, statically typed language win on
+ programing safety, and performance. Statically language would suit for
+ interoperate with kernel, as kernel is wrote mainly in C, Need to note that
+ SystemTap and Dtrace both is statically language.
+
+ ktap choose dynamically typed language as initial implementation.
+
+**Q: Why we need ktap for event tracing? There already have a built-in ftrace**
+A: This also is a common question for all dynamic tracing tool, not only ktap.
+ ktap provide more flexibility than built-in tracing infrastructure. Suppose
+ you need print a global variable when tracepoint hit, or you want print
+ backtrace, even more, you want to store some info into associative array, and
+ display it in histogram style when tracing end, in these case, some of them
+ ftrace can take it, some of them ftrace can not.
+ Overall, ktap provide you with great flexibility to scripting your own trace
+ need.
+
+**Q: How about the performance? Is ktap slow?**
+A: ktap is not slow, the bytecode is very high-level, based on lua, the language
+ virtual machine is register-based(compare with stack-based), with little
+ instruction, the table data structure is heavily optimized in ktapvm.
+ ktap use per-cpu allocation in many place, without global locking scheme,
+ it's very fast when executing tracepoint callback.
+ Performance benchmark showing that the overhead of ktap running is nearly
+ 10%(store event name into associative array), compare with full speed
+ running without any tracepoint enabled.
+
+ ktap will optimize overhead all the time, hopefully the overhead will
+ decrease to little than 5%, even more.
+
+**Q: Why not porting a high level language implementation into kernel directly?
+ Like python/JVM?**
+A: I take serious on the size of vm and memory footprint. Python vm is large,
+ it's not suit to embed into kernel, and python have some functionality
+ which we don't need.
+
+ The bytecode of other high level language is also big, ktap only have 32
+ bytecodes, python/java/erlang have nearly two hundred bytecodes.
+ There also have some problems when porting those language into kernel,
+ userspace programming have many differences with kernel programming,
+ like float numbers, handle sleeping code carefully in kernel, deadloop is
+ not allowed in kernel, multi-thread management, etc.., so it's impossible
+ to porting language implementation into kernel with little adaption work.
+
+**Q: What's the status of ktap now?**
+A: Basically it works on x86-32, x86-64, powerpc, arm, it also could work for
+ other hardware architecture, but not proven yet(I don't have enough hardware
+ to test)
+ If you found some bug, fix it on you own programming skill, or report to me.
+
+**Q: How to hack ktap? I want to write some extensions onto ktap.**
+A: welcome hacking.
+ You can write your own library to fulfill your specific need,
+ you can write any script as you want.
+
+**Q: What's the plan of ktap? any roadmap?**
+A: the current plan is deliver stable ktapvm kernel modules, more ktap script,
+ and bugfix.

-/**
- * "cvmx-usb.h" defines a set of low level USB functions to help
- * developers create Octeon USB drivers for various operating
- * systems. These functions provide a generic API to the Octeon
- * USB blocks, hiding the internal hardware specific
- * operations.
- *
- * At a high level the device driver needs to:
- *
- * - Call cvmx_usb_get_num_ports() to get the number of
- * supported ports.
- * - Call cvmx_usb_initialize() for each Octeon USB port.
- * - Enable the port using cvmx_usb_enable().
- * - Either periodically, or in an interrupt handler, call
- * cvmx_usb_poll() to service USB events.
- * - Manage pipes using cvmx_usb_open_pipe() and
- * cvmx_usb_close_pipe().
- * - Manage transfers using cvmx_usb_submit_*() and
- * cvmx_usb_cancel*().
- * - Shutdown USB on unload using cvmx_usb_shutdown().
- *
- * To monitor USB status changes, the device driver must use
- * cvmx_usb_register_callback() to register for events that it
- * is interested in. Below are a few hints on successfully
- * implementing a driver on top of this API.
- *
- * == Initialization ==
- *
- * When a driver is first loaded, it is normally not necessary
- * to bring up the USB port completely. Most operating systems
- * expect to initialize and enable the port in two independent
- * steps. Normally an operating system will probe hardware,
- * initialize anything found, and then enable the hardware.
- *
- * In the probe phase you should:
- * - Use cvmx_usb_get_num_ports() to determine the number of
- * USB port to be supported.
- * - Allocate space for a struct cvmx_usb_state for each
- * port.
- * - Tell the operating system about each port
- *
- * In the initialization phase you should:
- * - Use cvmx_usb_initialize() on each port.
- * - Do not call cvmx_usb_enable(). This leaves the USB port in
- * the disabled state until the operating system is ready.
- *
- * Finally, in the enable phase you should:
- * - Call cvmx_usb_enable() on the appropriate port.
- * - Note that some operating system use a RESET instead of an
- * enable call. To implement RESET, you should call
- * cvmx_usb_disable() followed by cvmx_usb_enable().
- *
- * == Locking ==
- *
- * All of the functions in the cvmx-usb API assume exclusive
- * access to the USB hardware and internal data structures. This
- * means that the driver must provide locking as necessary.
- *
- * In the single CPU state it is normally enough to disable
- * interrupts before every call to cvmx_usb*() and enable them
- * again after the call is complete. Keep in mind that it is
- * very common for the callback handlers to make additional
- * calls into cvmx-usb, so the disable/enable must be protected
- * against recursion. As an example, the Linux kernel
- * local_irq_save() and local_irq_restore() are perfect for this
- * in the non SMP case.
- *
- * In the SMP case, locking is more complicated. For SMP you not
- * only need to disable interrupts on the local core, but also
- * take a lock to make sure that another core cannot call
- * cvmx-usb.
- *
- * == Port callback ==
- *
- * The port callback prototype needs to look as follows:
- *
- * void port_callback(struct cvmx_usb_state *usb,
- * enum cvmx_usb_callback reason,
- * enum cvmx_usb_complete status,
- * int pipe_handle,
- * int submit_handle,
- * int bytes_transferred,
- * void *user_data);
- * - "usb" is the struct cvmx_usb_state for the port.
- * - "reason" will always be CVMX_USB_CALLBACK_PORT_CHANGED.
- * - "status" will always be CVMX_USB_COMPLETE_SUCCESS.
- * - "pipe_handle" will always be -1.
- * - "submit_handle" will always be -1.
- * - "bytes_transferred" will always be 0.
- * - "user_data" is the void pointer originally passed along
- * with the callback. Use this for any state information you
- * need.
- *
- * The port callback will be called whenever the user plugs /
- * unplugs a device from the port. It will not be called when a
- * device is plugged / unplugged from a hub connected to the
- * root port. Normally all the callback needs to do is tell the
- * operating system to poll the root hub for status. Under
- * Linux, this is performed by calling usb_hcd_poll_rh_status().
- * In the Linux driver we use "user_data". to pass around the
- * Linux "hcd" structure. Once the port callback completes,
- * Linux automatically calls octeon_usb_hub_status_data() which
- * uses cvmx_usb_get_status() to determine the root port status.
- *
- * == Complete callback ==
- *
- * The completion callback prototype needs to look as follows:
- *
- * void complete_callback(struct cvmx_usb_state *usb,
- * enum cvmx_usb_callback reason,
- * enum cvmx_usb_complete status,
- * int pipe_handle,
- * int submit_handle,
- * int bytes_transferred,
- * void *user_data);
- * - "usb" is the struct cvmx_usb_state for the port.
- * - "reason" will always be CVMX_USB_CALLBACK_TRANSFER_COMPLETE.
- * - "status" will be one of the cvmx_usb_complete enumerations.
- * - "pipe_handle" is the handle to the pipe the transaction
- * was originally submitted on.
- * - "submit_handle" is the handle returned by the original
- * cvmx_usb_submit_* call.
- * - "bytes_transferred" is the number of bytes successfully
- * transferred in the transaction. This will be zero on most
- * error conditions.
- * - "user_data" is the void pointer originally passed along
- * with the callback. Use this for any state information you
- * need. For example, the Linux "urb" is stored in here in the
- * Linux driver.
- *
- * In general your callback handler should use "status" and
- * "bytes_transferred" to tell the operating system the how the
- * transaction completed. Normally the pipe is not changed in
- * this callback.
- *
- * == Canceling transactions ==
- *
- * When a transaction is cancelled using cvmx_usb_cancel*(), the
- * actual length of time until the complete callback is called
- * can vary greatly. It may be called before cvmx_usb_cancel*()
- * returns, or it may be called a number of usb frames in the
- * future once the hardware frees the transaction. In either of
- * these cases, the complete handler will receive
- * CVMX_USB_COMPLETE_CANCEL.
- *
- * == Handling pipes ==
- *
- * USB "pipes" is a software construct created by this API to
- * enable the ordering of usb transactions to a device endpoint.
- * Octeon's underlying hardware doesn't have any concept
- * equivalent to "pipes". The hardware instead has eight
- * channels that can be used simultaneously to have up to eight
- * transaction in process at the same time. In order to maintain
- * ordering in a pipe, the transactions for a pipe will only be
- * active in one hardware channel at a time. From an API user's
- * perspective, this doesn't matter but it can be helpful to
- * keep this in mind when you are probing hardware while
- * debugging.
- *
- * Also keep in mind that usb transactions contain state
- * information about the previous transaction to the same
- * endpoint. Each transaction has a PID toggle that changes 0/1
- * between each sub packet. This is maintained in the pipe data
- * structures. For this reason, you generally cannot create and
- * destroy a pipe for every transaction. A sequence of
- * transaction to the same endpoint must use the same pipe.
- *
- * == Root Hub ==
- *
- * Some operating systems view the usb root port as a normal usb
- * hub. These systems attempt to control the root hub with
- * messages similar to the usb 2.0 spec for hub control and
- * status. For these systems it may be necessary to write
- * function to decode standard usb control messages into
- * equivalent cvmx-usb API calls.
- *
- * == Interrupts ==
- *
- * If you plan on using usb interrupts, cvmx_usb_poll() must be
- * called on every usb interrupt. It will read the usb state,
- * call any needed callbacks, and schedule transactions as
- * needed. Your device driver needs only to hookup an interrupt
- * handler and call cvmx_usb_poll(). Octeon's usb port 0 causes
- * CIU bit CIU_INT*_SUM0[USB] to be set (bit 56). For port 1,
- * CIU bit CIU_INT_SUM1[USB1] is set (bit 17). How these bits
- * are turned into interrupt numbers is operating system
- * specific. For Linux, there are the convenient defines
- * OCTEON_IRQ_USB0 and OCTEON_IRQ_USB1 for the IRQ numbers.
- *
- * If you aren't using interrupts, simple call cvmx_usb_poll()
- * in your main processing loop.
