  19 +* Mediatek Thermal
  20 +
  21 +This describes the device tree binding for the Mediatek thermal controller
  22 +which measures the on-SoC temperatures. This device does not have its own ADC,
  23 +instead it directly controls the AUXADC via AHB bus accesses. For this reason
  24 +this device needs phandles to the AUXADC.
  25 +
  26 +Required properties:
  27 +- compatible: "mediatek,mt8173-thermal"
  28 +- reg: Address range of the thermal controller
  29 +- interrupts: IRQ for the thermal controller
  30 +- clocks, clock-names: Clocks needed for the thermal controller. required
  31 +                       clocks are:
  32 +               "therm":        Main clock needed for register access
  33 +               "auxadc":       The AUXADC clock
  34 +- resets, reset-names: Reference to the reset controller controlling the thermal
  35 +                       controller. Required reset-names:
  36 +               "therm":        The main reset line
  37 +- auxadc: A phandle to the AUXADC which the thermal controller uses
  38 +- apmixedsys: A phandle to the APMIXEDSYS controller.
  39 +- #thermal-sensor-cells : Should be 1. See ./thermal.txt for a description
  40 +
  41 +Example:
  42 +
  43 +       thermal: thermal@1100b000 {
  44 +               #thermal-sensor-cells = <1>;
  45 +               compatible = "mediatek,mt8173-thermal";
  46 +               reg = <0 0x1100b000 0 0x1000>;
  47 +               interrupts = <0 70 IRQ_TYPE_LEVEL_LOW>;
  48 +               clocks = <&pericfg CLK_PERI_THERM>, <&pericfg CLK_PERI_AUXADC>;
  49 +               clock-names = "therm", "auxadc";
  50 +               resets = <&pericfg MT8173_PERI_THERM_SW_RST>;
  51 +               reset-names = "therm";
  52 +               auxadc = <&auxadc>;
  53 +               apmixedsys = <&apmixedsys>;
  54 +       };
