+Code of Conflict
+----------------
+
+The Linux kernel development effort is a very personal process compared
+to "traditional" ways of developing software. Your code and ideas
+behind it will be carefully reviewed, often resulting in critique and
+criticism. The review will almost always require improvements to the
+code before it can be included in the kernel. Know that this happens
+because everyone involved wants to see the best possible solution for
+the overall success of Linux. This development process has been proven
+to create the most robust operating system kernel ever, and we do not
+want to do anything to cause the quality of submission and eventual
+result to ever decrease.
+
+If however, anyone feels personally abused, threatened, or otherwise
+uncomfortable due to this process, that is not acceptable. If so,
+please contact the Linux Foundation's Technical Advisory Board at
+<tab@lists.linux-foundation.org>, or the individual members, and they
+will work to resolve the issue to the best of their ability. For more
+information on who is on the Technical Advisory Board and what their
+role is, please see:
+ http://www.linuxfoundation.org/programs/advisory-councils/tab
+
+As a reviewer of code, please strive to keep things civil and focused on
+the technical issues involved. We are all humans, and frustrations can
+be high on both sides of the process. Try to keep in mind the immortal
+words of Bill and Ted, "Be excellent to each other."

+Renesas Bus State Controller (BSC)
+==================================
+
+The Renesas Bus State Controller (BSC, sometimes called "LBSC within Bus
+Bridge", or "External Bus Interface") can be found in several Renesas ARM SoCs.
+It provides an external bus for connecting multiple external devices to the
+SoC, driving several chip select lines, for e.g. NOR FLASH, Ethernet and USB.
+
+While the BSC is a fairly simple memory-mapped bus, it may be part of a PM
+domain, and may have a gateable functional clock.
+Before a device connected to the BSC can be accessed, the PM domain
+containing the BSC must be powered on, and the functional clock
+driving the BSC must be enabled.
+
+The bindings for the BSC extend the bindings for "simple-pm-bus".
+
+
+Required properties
+ - compatible: Must contain an SoC-specific value, and "renesas,bsc" and
+ "simple-pm-bus" as fallbacks.
+ SoC-specific values can be:
+ "renesas,bsc-r8a73a4" for R-Mobile APE6 (r8a73a4)
+ "renesas,bsc-sh73a0" for SH-Mobile AG5 (sh73a0)
+ - #address-cells, #size-cells, ranges: Must describe the mapping between
+ parent address and child address spaces.
+ - reg: Must contain the base address and length to access the bus controller.
+
+Optional properties:
+ - interrupts: Must contain a reference to the BSC interrupt, if available.
+ - clocks: Must contain a reference to the functional clock, if available.
+ - power-domains: Must contain a reference to the PM domain, if available.
+
+
+Example:
+
+ bsc: bus@fec10000 {
+ compatible = "renesas,bsc-sh73a0", "renesas,bsc",
+ "simple-pm-bus";
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges = <0 0 0x20000000>;
+ reg = <0xfec10000 0x400>;
+ interrupts = <0 39 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&zb_clk>;
+ power-domains = <&pd_a4s>;
+ };
--- /dev/null
+Simple Power-Managed Bus
+========================
+
+A Simple Power-Managed Bus is a transparent bus that doesn't need a real
+driver, as it's typically initialized by the boot loader.
+
+However, its bus controller is part of a PM domain, or under the control of a
+functional clock. Hence, the bus controller's PM domain and/or clock must be
+enabled for child devices connected to the bus (either on-SoC or externally)
+to function.
+
+While "simple-pm-bus" follows the "simple-bus" set of properties, as specified
+in ePAPR, it is not an extension of "simple-bus".
+
+
+Required properties:
+ - compatible: Must contain at least "simple-pm-bus".
+ Must not contain "simple-bus".
+ It's recommended to let this be preceded by one or more
+ vendor-specific compatible values.
+ - #address-cells, #size-cells, ranges: Must describe the mapping between
+ parent address and child address spaces.
+
+Optional platform-specific properties for clock or PM domain control (at least
+one of them is required):
+ - clocks: Must contain a reference to the functional clock(s),
+ - power-domains: Must contain a reference to the PM domain.
+Please refer to the binding documentation for the clock and/or PM domain
+providers for more details.
+
+
+Example:
+
+ bsc: bus@fec10000 {
+ compatible = "renesas,bsc-sh73a0", "renesas,bsc",
+ "simple-pm-bus";
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges = <0 0 0x20000000>;
+ reg = <0xfec10000 0x400>;
+ interrupts = <0 39 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&zb_clk>;

APM X-Gene SoC.
Required properties for all the ethernet interfaces:
-- compatible: Should be "apm,xgene-enet"
+- compatible: Should state binding information from the following list,
+ - "apm,xgene-enet": RGMII based 1G interface
+ - "apm,xgene1-sgenet": SGMII based 1G interface
+ - "apm,xgene1-xgenet": XFI based 10G interface
- reg: Address and length of the register set for the device. It contains the
information of registers in the same order as described by reg-names

providing multiple PM domains (e.g. power controllers), but can be any value
as specified by device tree binding documentation of particular provider.
+Optional properties:
+ - power-domains : A phandle and PM domain specifier as defined by bindings of
+ the power controller specified by phandle.
+ Some power domains might be powered from another power domain (or have
+ other hardware specific dependencies). For representing such dependency
+ a standard PM domain consumer binding is used. When provided, all domains
+ created by the given provider should be subdomains of the domain
+ specified by this binding. More details about power domain specifier are
+ available in the next section.
+
Example:
power: power-controller@12340000 {
The node above defines a power controller that is a PM domain provider and
expects one cell as its phandle argument.
+Example 2:
+
+ parent: power-controller@12340000 {
+ compatible = "foo,power-controller";
+ reg = <0x12340000 0x1000>;
+ #power-domain-cells = <1>;
+ };
+
+ child: power-controller@12340000 {
+ compatible = "foo,power-controller";
+ reg = <0x12341000 0x1000>;
+ power-domains = <&parent 0>;
+ #power-domain-cells = <1>;
+ };
+
+The nodes above define two power controllers: 'parent' and 'child'.
+Domains created by the 'child' power controller are subdomains of '0' power
+domain provided by the 'parent' power controller.
+

The IRQF_NO_SUSPEND flag is used to indicate that to the IRQ subsystem when
requesting a special-purpose interrupt. It causes suspend_device_irqs() to
-leave the corresponding IRQ enabled so as to allow the interrupt to work all
-the time as expected.
+leave the corresponding IRQ enabled so as to allow the interrupt to work as
+expected during the suspend-resume cycle, but does not guarantee that the
+interrupt will wake the system from a suspended state -- for such cases it is
+necessary to use enable_irq_wake().
Note that the IRQF_NO_SUSPEND flag affects the entire IRQ and not just one
user of it. Thus, if the IRQ is shared, all of the interrupt handlers installed
IRQF_NO_SUSPEND and enable_irq_wake()
-------------------------------------
-There are no valid reasons to use both enable_irq_wake() and the IRQF_NO_SUSPEND
-flag on the same IRQ.
+There are very few valid reasons to use both enable_irq_wake() and the
+IRQF_NO_SUSPEND flag on the same IRQ, and it is never valid to use both for the
+same device.
First of all, if the IRQ is not shared, the rules for handling IRQF_NO_SUSPEND
interrupts (interrupt handlers are invoked after suspend_device_irqs()) are
Second, both enable_irq_wake() and IRQF_NO_SUSPEND apply to entire IRQs and not
to individual interrupt handlers, so sharing an IRQ between a system wakeup
-interrupt source and an IRQF_NO_SUSPEND interrupt source does not make sense.
+interrupt source and an IRQF_NO_SUSPEND interrupt source does not generally
+make sense.
+
+In rare cases an IRQ can be shared between a wakeup device driver and an
+IRQF_NO_SUSPEND user. In order for this to be safe, the wakeup device driver
+must be able to discern spurious IRQs from genuine wakeup events (signalling
+the latter to the core with pm_system_wakeup()), must use enable_irq_wake() to
+ensure that the IRQ will function as a wakeup source, and must request the IRQ
+with IRQF_COND_SUSPEND to tell the core that it meets these requirements. If
+these requirements are not met, it is not valid to use IRQF_COND_SUSPEND.

+ * R-Car Generation 2 da9063/da9210 regulator quirk
+ *
+ * The r8a7790/lager and r8a7791/koelsch development boards have da9063 and
+ * da9210 regulators. Both regulators have their interrupt request lines tied
+ * to the same interrupt pin (IRQ2) on the SoC.
+ *
+ * After cold boot or da9063-induced restart, both the da9063 and da9210 seem
+ * to assert their interrupt request lines. Hence as soon as one driver
+ * requests this irq, it gets stuck in an interrupt storm, as it only manages
+ * to deassert its own interrupt request line, and the other driver hasn't
+ * installed an interrupt handler yet.
+ *
+ * To handle this, install a quirk that masks the interrupts in both the
+ * da9063 and da9210. This quirk has to run after the i2c master driver has
+ * been initialized, but before the i2c slave drivers are initialized.
