- 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>;
- };
