+* 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_clk" for the transfer-clock, and "tsadc_pclk" for
+    the peripheral clock.
+Optional properties:
+- clock-frequency : Thermal sensor's clock frequency.
+- pinctrl-names : Should contain only one value - "default".
+- pinctrl-0 : Should contain only one value - &tsadc_int.
+- passive-temp : Temperature of trip 0.
+- critical-temp : Temperature of trip 1.
+- force-shut-temp : Temperature of force shut down.
+Example:
+
+tsadc: tsadc@ff280000 {
+	compatible = "rockchip,rk3288-tsadc";
+	reg = <0xff280000 0x100>;
+	interrupts = <GIC_SPI 37 IRQ_TYPE_LEVEL_HIGH>;
+	clock-frequency = <10000>;
+	clocks = <&cru SCLK_TSADC>, <&cru PCLK_TSADC>;
+	clock-names = "tsadc_clk", "tsadc_pclk";
+	pinctrl-names = "default";
+	pinctrl-1 = <&tsadc_int>;
+	passive-temp = <80>;
+	critical-temp = <100>;
+	force-shut-temp = <120>;
+};
