* Tegra114/124 SOC_THERM

** Thermal node required properties:

- compatible : "nvidia,tegra124-soctherm" or "nvidia,tegra114-soctherm".
- reg : address range of the thermal sensor registers;
- interrupts : irq for soc_therm.
- clocks : clocks for soc_therm.
- clock-names : clock names for soc_therm.
- pmu-16bit-ops : 16bit ops.
- pmu-i2c-addr : i2c slave address.
- i2c-controller-id : i2c controller id.
- poweroff-reg-addr : pmu poweroff register address.
- poweroff-reg-data : pmu poweroff register data.

** Optional properties:
- cpu-edp-cdev: handle of the cpu-edp thermal recation node,
which will be bound with this soc_therm thermal zone.

Example soc_therm node:

soc_therm {
	compatible = "nvidia,tegra124-soctherm";
	reg = <0x700e2000 0x1000>;
	clocks = <&tegra_car 78>, <&tegra_car 100>;
	clock-names = "soc_therm", "tsensor";
	pmu-16bit-ops = <0>;
	pmu-i2c-addr = <0x40>;
	i2c-controller-id = <4>;
	poweroff-reg-addr = <0x36>;
	poweroff-reg-data = <0x2>;

	cpu-edp-cdev = <&{/cpu_edp_cdev_action}>;
