+Annapurna Labs Alpine Platform Device Tree Bindings
+---------------------------------------------------------------
+
+Boards in the Alpine family shall have the following properties:
+
+* Required root node properties:
+compatible: must contain "al,alpine"
+
+* Example:
+
+/ {
+ model = "Annapurna Labs Alpine Dev Board";
+ compatible = "al,alpine";
+
+ ...
+}
+
+* CPU node:
+
+The Alpine platform includes cortex-a15 cores.
+enable-method: must be "al,alpine-smp" to allow smp [1]
+
+Example:
+
+cpus {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ enable-method = "al,alpine-smp";
+
+ cpu@0 {
+ compatible = "arm,cortex-a15";

+
+
+* Alpine CPU resume registers
+
+The CPU resume register are used to define required resume address after
+reset.
+
+Properties:
+- compatible : Should contain "al,alpine-cpu-resume".
+- reg : Offset and length of the register set for the device
+
+Example:
+
+cpu_resume {
+ compatible = "al,alpine-cpu-resume";
+ reg = <0xfbff5ed0 0x30>;
+};
+
+* Alpine System-Fabric Service Registers
+
+The System-Fabric Service Registers allow various operation on CPU and
+system fabric, like powering CPUs off.
+
+Properties:
+- compatible : Should contain "al,alpine-sysfabric-service" and "syscon".
+- reg : Offset and length of the register set for the device
+
+Example:
+

+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 -

The SAW2 is a wrapper around the Subsystem Power Manager (SPM) and the
