+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."

+QCOM Idle States for cpuidle driver
+
+ARM provides idle-state node to define the cpuidle states, as defined in [1].
+cpuidle-qcom is the cpuidle driver for Qualcomm SoCs and uses these idle
+states. Idle states have different enter/exit latency and residency values.
+The idle states supported by the QCOM SoC are defined as -
+
+ * Standby
+ * Retention
+ * Standalone Power Collapse (Standalone PC or SPC)
+ * Power Collapse (PC)
+
+Standby: Standby does a little more in addition to architectural clock gating.
+When the WFI instruction is executed the ARM core would gate its internal
+clocks. In addition to gating the clocks, QCOM cpus use this instruction as a
+trigger to execute the SPM state machine. The SPM state machine waits for the
+interrupt to trigger the core back in to active. This triggers the cache
+hierarchy to enter standby states, when all cpus are idle. An interrupt brings
+the SPM state machine out of its wait, the next step is to ensure that the
+cache hierarchy is also out of standby, and then the cpu is allowed to resume
+execution. This state is defined as a generic ARM WFI state by the ARM cpuidle
+driver and is not defined in the DT. The SPM state machine should be
+configured to execute this state by default and after executing every other
+state below.
+
+Retention: Retention is a low power state where the core is clock gated and
+the memory and the registers associated with the core are retained. The
+voltage may be reduced to the minimum value needed to keep the processor
+registers active. The SPM should be configured to execute the retention
+sequence and would wait for interrupt, before restoring the cpu to execution
+state. Retention may have a slightly higher latency than Standby.
+
+Standalone PC: A cpu can power down and warmboot if there is a sufficient time
+between the time it enters idle and the next known wake up. SPC mode is used
+to indicate a core entering a power down state without consulting any other
+cpu or the system resources. This helps save power only on that core. The SPM
+sequence for this idle state is programmed to power down the supply to the
+core, wait for the interrupt, restore power to the core, and ensure the
+system state including cache hierarchy is ready before allowing core to
+resume. Applying power and resetting the core causes the core to warmboot
+back into Elevation Level (EL) which trampolines the control back to the
+kernel. Entering a power down state for the cpu, needs to be done by trapping
+into a EL. Failing to do so, would result in a crash enforced by the warm boot
+code in the EL for the SoC. On SoCs with write-back L1 cache, the cache has to
+be flushed in s/w, before powering down the core.
+
+Power Collapse: This state is similar to the SPC mode, but distinguishes
+itself in that the cpu acknowledges and permits the SoC to enter deeper sleep
+modes. In a hierarchical power domain SoC, this means L2 and other caches can
+be flushed, system bus, clocks - lowered, and SoC main XO clock gated and
+voltages reduced, provided all cpus enter this state. Since the span of low
+power modes possible at this state is vast, the exit latency and the residency
+of this low power mode would be considered high even though at a cpu level,
+this essentially is cpu power down. The SPM in this state also may handshake
+with the Resource power manager (RPM) processor in the SoC to indicate a
+complete application processor subsystem shut down.
+
+The idle-state for QCOM SoCs are distinguished by the compatible property of
+the idle-states device node.
+
+The devicetree representation of the idle state should be -
+
+Required properties:
+
+- compatible: Must be one of -

+
+Other required and optional properties are specified in [1].

The SAW2 is a wrapper around the Subsystem Power Manager (SPM) and the
Adaptive Voltage Scaling (AVS) hardware. The SPM is a programmable
-micro-controller that transitions a piece of hardware (like a processor or
+power-controller that transitions a piece of hardware (like a processor or
subsystem) into and out of low power modes via a direct connection to
the PMIC. It can also be wired up to interact with other processors in the
system, notifying them when a low power state is entered or exited.
+Multiple revisions of the SAW hardware are supported using these Device Nodes.
+SAW2 revisions differ in the register offset and configuration data. Also, the
+same revision of the SAW in different SoCs may have different configuration
+data due the the differences in hardware capabilities. Hence the SoC name, the
+version of the SAW hardware in that SoC and the distinction between cpu (big
+or Little) or cache, may be needed to uniquely identify the SAW register
+configuration and initialization data. The compatible string is used to
+indicate this parameter.

Required properties (as per of_videomode_helper):
- atmel,disable : Should be present if you want to disable the watchdog.
- atmel,idle-halt : Should be present if you want to stop the watchdog when
entering idle state.
+ CAUTION: This property should be used with care, it actually makes the
+ watchdog not counting when the CPU is in idle state, therefore the
+ watchdog reset time depends on mean CPU usage and will not reset at all
+ if the CPU stop working while it is in idle state, which is probably
+ not what you want.
- atmel,dbg-halt : Should be present if you want to stop the watchdog when
entering debug state.

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.

+ * Window invoke the standard adapter Big-Endian to PCI-E Link
+ * Little-Endian "swizzel." As a result, if we have the following
+ * data in adapter memory:
+ *
+ * Memory: ... | b0 | b1 | b2 | b3 | ...
+ * Address: i+0 i+1 i+2 i+3
+ *
+ * Then a read of the adapter memory via the PCI-E Memory Window
+ * will yield:
+ *
+ * x = readl(i)
+ * 31 0
+ * [ b3 | b2 | b1 | b0 ]
+ *
+ * If this value is stored into local memory on a Little-Endian system
+ * it will show up correctly in local memory as:
+ *
+ * ( ..., b0, b1, b2, b3, ... )
+ *
+ * But on a Big-Endian system, the store will show up in memory
+ * incorrectly swizzled as:
+ *
+ * ( ..., b3, b2, b1, b0, ... )
+ *
+ * So we need to account for this in the reads and writes to the
+ * PCI-E Memory Window below by undoing the register read/write
+ * swizzels.
