MAINTIANERS: just use Mike gmail e-mail for contact and pawn the serial driver off onto Sonic
[Blackfin] arch: remove old I2C BF54x porting.
[Blackfin] arch: Add the semtimedop syscall. Upstream uClibc doesn't compile without it.
[Blackfin] arch: fix bug kernel boot message: memory information is not reasonable
[Blackfin] arch: use common flash driver to setup partitions rather than the bf5xx-flash driver
[Blackfin] arch: Fix bug - kernel build with Debug option enabled fails to boot up
[Blackfin] arch: Fix bug Only RTC interrupt can wake up deeper sleep core.
[Blackfin] arch: Add proper SW System Reset delay sequence
[Blackfin] arch: Update copyright date
[Blackfin] arch: GPIO API cleanup and anomaly update
[Blackfin] arch: Fix BUG gpio_direction_output API is not compatitable with GENERIC_GPIO API interface
[Blackfin] arch: Initial checkin of the memory protection support.
[Blackfin] arch: set_bfin_dma_config shouldnt set SYNC or RESTART by default - add argument or option
[Blackfin] arch: Add some comments - fix semicolons
[Blackfin] arch: move all code related to CPLB handling into a new subdirectory under kernel/
[Blackfin] arch: print out list of modules if kernel is crashing and tell people if the kernel is tainted
[Blackfin] arch: enable generic GPIO based I2C driver in STAMP-BF533, EZKIT-BF533 and EZKIT-BF561 boards
[Blackfin] arch: Don't oops_in_progress if single step is comming from the kernel
[Blackfin] arch: Fix BUG - kernel sometimes would stuck with KEYBOARD_GPIO on
[Blackfin] arch: update to latest anomaly sheets
...
Zero-bytes transfers would leave the bus transaction unfinished
(no i2c stop is sent), with the following transfer actually
sending the slave address to the previously addressed device,
resulting in weird device failures (e.g. reset minute register
values in my RTC).
This patch instructs the controller to send an I2C STOP right after
the slave address in case of a zero-byte transfer.

i2c-remove-redundant-i2c_client-list.patch
This goes on top of the patch removing most i2c_adapter.clients usage,
updating i2c_attach_client:
- Don't call device_register() while holding clist_lock. This
removes a self-deadlock when on the i2c_driver.probe() path,
for drivers that need to attach new devices (e.g. dummies).
- Remove a redundant address check. The driver model core does
this as a consequence of guaranteeing unique names.
- Move the "device registered" diagnostic so that it never lies;
previously, on error paths it would falsely report success.

i2c: Drivers stop using the redundant client list
The redundant i2c client list maintained by i2c-core is going away
soon, so drivers should stop using it now. Instead, they can use the
standard iterator provided by the device driver model
(device_for_each_child).

i2c: Stop using the redundant client list
The i2c_adapter.clients list of i2c_client nodes duplicates driver
model state. This patch starts removing that list, letting us remove
most existing users of those i2c-core lists.
* The core I2C code now iterates over the driver model's list instead
of the i2c-internal one in some places where it's safe:
- Passing a command/ioctl to each client, a mechanims
used almost exclusively by DVB adapters;
- Device address checking, in both i2c-core and i2c-dev.
* Provide i2c_verify_client() to use with driver model iterators.
* Flag the relevant i2c_adapter and i2c_client fields as deprecated,
to help prevent new users from appearing.
For the moment the list needs to stick around, since some issues show
up when deleting devices created by legacy I2C drivers. (They don't
follow standard driver model rules. Removing those devices can cause
self-deadlocks.)

i2c: Let the user specify PCI driver data through new_id
The i2c-amd756 and i2c-viapro drivers make use of the driver_data
field of the PCI device ID. When adding device IDs dynamically (by
writing to the new_id sysfs file) you cannot set the value of this
field by default. It has to be allowed explicitly. Do that, and
check the value so that the user can't crash the kernel accidentally.

i2c-i801: Implement I2C block read support
I2C block read is supported since the ICH5. I couldn't get it to work
using the block buffer, so it's using the old-style byte-by-byte mode

Note: I'm also updating the driver author... The i2c-i801 driver was
really written by Mark Studebaker, even though he based his work on
the i2c-piix4 driver which was written by Philip Edelbrock.
