* Temperature Sensor on hisilicon SoCs
** Required properties :
- compatible: "hisilicon,tsensor".
- reg: physical base address of thermal sensor and length of memory mapped
region.
- interrupt: The interrupt number to the cpu. Defines the interrupt used
by /SOCTHERM/tsensor.
- clock-names: Input clock name, should be 'thermal_clk'.
- clocks: phandles for clock specified in "clock-names" property.
- #thermal-sensor-cells: Should be 1. See ./thermal.txt for a description.
Example :
tsensor: tsensor@0,f7030700 {
compatible = "hisilicon,tsensor";
reg = <0x0 0xf7030700 0x0 0x1000>;
interrupts = <0 7 0x4>;
clocks = <&sys_ctrl HI6220_TSENSOR_CLK>;
clock-names = "thermal_clk";
#thermal-sensor-cells = <1>;
}
