MediaTek SCPSYS
===============

The System Control Processor System (SCPSYS) has several power management
related tasks in the system. The tasks include thermal measurement, dynamic
voltage frequency scaling (DVFS), interrupt filter and lowlevel sleep control.
The System Power Manager (SPM) inside the SCPSYS is for the MTCMOS power
domain control.

The driver implements the Generic PM domain bindings described in
power/power_domain.txt. It provides the power domains defined in
include/dt-bindings/power/mt8173-power.h.

Required properties:
- compatible: Must be "mediatek,mt8173-scpsys"
- #power-domain-cells: Must be 1
- reg: Address range of the SCPSYS unit
- infracfg: must contain a phandle to the infracfg controller

Example:

	scpsys: scpsys@10006000 {
		#power-domain-cells = <1>;
		compatible = "mediatek,mt8173-scpsys";
		reg = <0 0x10006000 0 0x1000>;
		infracfg = <&infracfg>;
	};

Example consumer:

	afe: mt8173-afe-pcm@11220000 {
		compatible = "mediatek,mt8173-afe-pcm";
		power-domains = <&scpsys MT8173_POWER_DOMAIN_AUDIO>;
	};
