-* Temperature Sensor ADC (TSADC) on rockchip SoCs
-
-Required properties:
-- compatible : should be "rockchip,<name>-tsadc"
- "rockchip,px30-tsadc": found on PX30 SoCs
- "rockchip,rv1108-tsadc": found on RV1108 SoCs
- "rockchip,rk3228-tsadc": found on RK3228 SoCs
- "rockchip,rk3288-tsadc": found on RK3288 SoCs
- "rockchip,rk3328-tsadc": found on RK3328 SoCs
- "rockchip,rk3368-tsadc": found on RK3368 SoCs
- "rockchip,rk3399-tsadc": found on RK3399 SoCs
-- reg : physical base address of the controller and length of memory mapped
- region.
-- interrupts : The interrupt number to the cpu. The interrupt specifier format
- depends on the interrupt controller.
-- clocks : Must contain an entry for each entry in clock-names.
-- clock-names : Shall be "tsadc" for the converter-clock, and "apb_pclk" for
- the peripheral clock.
-- resets : Must contain an entry for each entry in reset-names.
- See ../reset/reset.txt for details.
-- reset-names : Must include the name "tsadc-apb".
-- pinctrl-names : The pin control state names;
-- pinctrl-0 : The "init" pinctrl state, it will be set before device probe.
-- pinctrl-1 : The "default" pinctrl state, it will be set after reset the
- TSADC controller.
-- pinctrl-2 : The "sleep" pinctrl state, it will be in for suspend.
-- #thermal-sensor-cells : Should be 1. See Documentation/devicetree/bindings/thermal/thermal-sensor.yaml for a description.
-
-Optional properties:
-- rockchip,hw-tshut-temp : The hardware-controlled shutdown temperature value.
-- rockchip,hw-tshut-mode : The hardware-controlled shutdown mode 0:CRU 1:GPIO.
-- rockchip,hw-tshut-polarity : The hardware-controlled active polarity 0:LOW
- 1:HIGH.
-- rockchip,grf : The phandle of the syscon node for the general register file.
-
-Exiample:
-tsadc: tsadc@ff280000 {
- compatible = "rockchip,rk3288-tsadc";
- reg = <0xff280000 0x100>;
- interrupts = <GIC_SPI 37 IRQ_TYPE_LEVEL_HIGH>;
- clocks = <&cru SCLK_TSADC>, <&cru PCLK_TSADC>;
- clock-names = "tsadc", "apb_pclk";
- resets = <&cru SRST_TSADC>;
- reset-names = "tsadc-apb";
- pinctrl-names = "init", "default", "sleep";
- pinctrl-0 = <&otp_gpio>;
- pinctrl-1 = <&otp_out>;
- pinctrl-2 = <&otp_gpio>;
- #thermal-sensor-cells = <1>;
- rockchip,hw-tshut-temp = <95000>;
- rockchip,hw-tshut-mode = <0>;
- rockchip,hw-tshut-polarity = <0>;
-};
-
-Example: referring to thermal sensors:
-thermal-zones {
- cpu_thermal: cpu_thermal {
- polling-delay-passive = <1000>; /* milliseconds */
- polling-delay = <5000>; /* milliseconds */
-
- /* sensor ID */
- thermal-sensors = <&tsadc 1>;
-
- trips {
- cpu_alert0: cpu_alert {
- temperature = <70000>; /* millicelsius */
- hysteresis = <2000>; /* millicelsius */
- type = "passive";
- };
- cpu_crit: cpu_crit {
- temperature = <90000>; /* millicelsius */
- hysteresis = <2000>; /* millicelsius */
- type = "critical";
- };
- };
-
- cooling-maps {
- map0 {
- trip = <&cpu_alert0>;
- cooling-device =
- <&cpu0 THERMAL_NO_LIMIT THERMAL_NO_LIMIT>;
- };
- };
- };
-};
