++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>;
++ };
