+* Temperature Sensor ADC (TSADC) on rockchip SoCs
+
+Required properties:
+- compatible : "rockchip,rk3288-tsadc"
+- 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.
+- #thermal-sensor-cells : Should be 1. See ./thermal.txt for a description.
+- hw-shut-temp : The hardware-controlled shutdown temperature value. +-
tsadc-tshut-mode : The hardware-controlled shutdown mode 0:CRU 1:GPIO. +-
tsadc-tshut-polarity : The hardware-controlled active polarity 0:LOW
1:HIGH. +
+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";
+ pinctrl-names = "default";
+ pinctrl-0 = <&otp_out>;
+ #thermal-sensor-cells = <1>;
+ hw-shut-temp = <125000>;
+ tsadc-tshut-mode = <0>;
+ tsadc-tshut-polarity = <0>;
these last 3 seem to be specific to this tsadc so should probably have a
"rockchip,"-prefix
Fixed.
e.g sync to driver
rockchip,hw-shut-temp = <125000>;
rockchip,tsadc-tshut-mode = <0>;
rockchip,tsadc-tshut-polarity = <0>;
I will sent next patch v17 in 1-2 days if this series patchs haven't
any problems.
Thanks.
