Binding for Thermal Sensor driver for BCM2835 SoCs.
Required parameters:
-------------------
compatible: should be one of: "brcm,bcm2835-thermal",
"brcm,bcm2836-thermal" or "brcm,bcm2837-thermal"
reg: Address range of the thermal registers.
clocks: Phandle of the clock used by the thermal sensor.
Example:
thermal: thermal@7e212000 {
compatible = "brcm,bcm2835-thermal";
reg = <0x7e212000 0x8>;
clocks = <&clocks BCM2835_CLOCK_TSENS>;
