		* MSM Subsystem Power Manager (spm-v2)

		S4 generation of MSMs have SPM hardware blocks to control the Application
		Processor Sub-System power. These SPM blocks run individual state machine
		to determine what the core (L2 or Krait/Scorpion) would do when the WFI
		instruction is executed by the core. The SAW hardware block handles SPM and
		AVS functionality for the cores.

		The devicetree representation of the SPM block should be:

		Required properties

		- compatible: "qcom,spm-v2"
		- reg: The physical address and the size of the SPM's memory mapped registers
		- qcom,cpu: phandle for the CPU that the SPM block is attached to. This field
		is required on only for SPMs that control the CPU. This field is not required
		for SPMs that control L2/CCI/L3
		- qcom,saw2-ver-reg: The location of the version register
		- qcom,name: The name with which a SPM device is identified by the power
		management code.

		----------------------------------------------------
		Non-PSCI targets should follow the rules shown below

		Required properties for only Non-PSCI targets:

		- qcom,saw2-cfg: SAW2 configuration register
		- qcom,saw2-spm-ctl: The SPM control register
		- qcom,saw2-spm-dly: Provides the values for the SPM delay command in the SPM
		sequence

		Optional properties for only Non-PSCI targets
		- reg-names: Register names for the physical address required if spm device
		has more than one physical addressed to be mapped. Allowed register
		names are: "saw-base", "q2s", "hw-flush", "slpreq"
		- qcom,saw2-avs-ctl: The AVS control register
		- qcom,saw2-avs-hysterisis: The AVS hysterisis register to delay the AVS
		controller requests
		- qcom,vctl-timeout-us: The timeout value in us to wait for voltage to change
		after sending the voltage command to the PMIC
		- qcom,saw2-avs-limit: The AVS limit register
		- qcom,saw2-avs-dly: The AVS delay register is used to specify the delay values
		between AVS controller requests
		- qcom,saw2-pmic-data0..7: Specify the pmic data value and the associated FTS
		index to send the PMIC data to
		- qcom,vctl-port: The PVC (PMIC Virtual Channel) port used for changing
		voltage
		- qcom,vctl-port-ub: The PVC (PMIC Virtual Channel) port used for changing
		voltage
		- qcom,phase-port: The PVC port used for changing the number of phases
		- qcom,pfm-port: The PVC port used for enabling PWM/PFM modes
		- qcom,cpu-vctl-mask: Mask of cpus, whose voltage the spm device can control.
		Depricated: Replaced with cpu-vctl-list when cpu phandles are available.
		- qcom,cpu-vctl-list: List of cpu node phandles, whose voltage the spm device
		can control.
		- qcom,use-qchannel-for-pc: Boolean property to specify if qchannel should be
		ignored when entering power collapse. If this property is set qchannel
		will not be ignored in power collapse.
		- qcom,supports-rpm-hs: Indicates that this SPM instance allow handshake with
		RPM processor when executing the sleep command in the SPM sequence. Supported
		only on SAW2 v3.0 and above.
		- qcom,use-spm-clock-gating: This boolean property is used to indicate that
		the SPM needs to be used for clock gating. Using the SPM for clock
		gating would result in auto clock gating being disabled. Use this on
		targets that do not support or do not use auto clock gating.
		- qcom,use-qchannel-for-wfi: This boolean property is used to indicate
		that the SPM gets triggerd by the qchannel and not by means of
		wfi. So a wfe could trigger a spm for clock gating as well.
		- modes: Lists all the available low power modes for the device

		Second level properties for modes

		Required properties (if modes node is available)
		- qcom,label: Specifies the mode name such as:
		qcom,saw2-spm-cmd-wfi: WFI mode
		qcom,saw2-spm-cmd-ret: Retention mode
		qcom,saw2-spm-cmd-spc: Standalone PC mode
		qcom,saw2-spm-cmd-pc: Power Collapse mode
		qcom,saw2-spm-cmd-gdhs: GDHS mode
		- qcom,sequence: Specifies sequence for the low power mode
		Optional properties
		- qcom,pc_mode: Specifies pc_mode bit should be set in the SPM control register
		- qcom,ret_mode: Specifies ret_mode bit should be set in the SPM control register
		- qcom,spm_en: Specifies spm_en bit should be set in the SPM control register
		- qcom,isar: Specifies isar bit should be set in the SPM control register
		Specify this property only if SPM should retain its start address at
		the end of the program.
		- qcom,slp_cmd_mode: Specifies slp_cmd_mode bit should be set in SPM control register.
		Adding this property results in SPM handshaking with RPM. Please remove
		the RPM handshake command from the sleep sequence, replace that with
		Sleep without RPM handshake command.
		- qcom,event_sync: Specifies event_sync byte should be set in SPM control
		register.

		can control.
