+* 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.

+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";
+};
+
+Example: referring to thermal sensors:
+thermal-zones {
+ cpu_thermal: cpu_thermal {
+ polling-delay-passive = <500>; /* milliseconds */
+ polling-delay = <1000>; /* milliseconds */
+
+ /* sensor ID */
