  21 +MediaTek SCPSYS
  22 +===============
  23 +
  24 +The System Control Processor System (SCPSYS) has several power management
  25 +related tasks in the system. The tasks include thermal measurement, dynamic
  26 +voltage frequency scaling (DVFS), interrupt filter and lowlevel sleep control.
  27 +The System Power Manager (SPM) inside the SCPSYS is for the MTCMOS power
  28 +domain control.
  29 +
  30 +The driver implements the Generic PM domain bindings described in
  31 +power/power_domain.txt. It provides the power domains defined in
  32 +include/dt-bindings/power/mt8173-power.h.
  33 +
  34 +Required properties:
  35 +- compatible: Must be "mediatek,mt8173-scpsys"
  36 +- #power-domain-cells: Must be 1
  37 +- reg: Address range of the SCPSYS unit
  38 +- infracfg: must contain a phandle to the infracfg controller
  39 +
  40 +Example:
  41 +
  42 +       scpsys: scpsys@10006000 {
  43 +               #power-domain-cells = <1>;
  44 +               compatible = "mediatek,mt8173-scpsys";
  45 +               reg = <0 0x10006000 0 0x1000>;
  46 +               infracfg = <&infracfg>;
  47 +       };
  48 +
  49 +Example consumer:
  50 +
  51 +       afe: mt8173-afe-pcm@11220000 {
  52 +               compatible = "mediatek,mt8173-afe-pcm";
  53 +               power-domains = <&scpsys MT8173_POWER_DOMAIN_AUDIO>;
  54 +       };
