* Renesas R-Car Gen3 Thermal

Required properties:
- compatible		: "renesas,thermal-<soctype>",
			  Examples with soctypes are:
			    - "renesas,thermal-r8a7795" (R-Car H3)
			    - "renesas,thermal-r8a7796" (R-Car M3)
- reg			: Address range of the thermal registers.
- #thermal-sensor-cells : Please see ./thermal.txt

Option properties:

- interrupts		: use interrupt

Example (non interrupt support):

thermal: thermal@0xe6198000 {
                        compatible = "renesas,thermal-r8a7795";
                        reg = <0 0xe6198000 0 0x5c>;
                };

thermal-zones {
	cpu_thermal: cpu-thermal {
		polling-delay-passive	= <250>;
		polling-delay		= <1000>;

		thermal-sensors = <&thermal>;
	};
};

Example (interrupt support):

thermal: thermal@0xe6198000 {
                        compatible = "renesas,thermal-r8a7795";
                        reg = <0 0xe6198000 0 0x5c>;
			interrupts = <GIC_SPI 67 IRQ_TYPE_LEVEL_HIGH>;
			             <GIC_SPI 68 IRQ_TYPE_LEVEL_HIGH>;
			             <GIC_SPI 69 IRQ_TYPE_LEVEL_HIGH>;
                };

thermal-zones {
	cpu_thermal: cpu-thermal {
		polling-delay-passive	= <250>;
		polling-delay		= <0>;

		thermal-sensors = <&thermal>;
	};
};

* Emergency shutdown for R-CAR Gen3
Emergency shutdown functionality provides the specific cooling mechanism
for R-CAR Gen3. In case of high temperature(e.g over 100 degrees),
it has the ability to rapidly cool down the system.

Required property:
- polling-delay:	The maximum number of milliseconds to wait between polls
  Type: unsigned	when checking temperature for emergency shutdown.
  Size: one cell

- on-temperature:       This value indicates the emergency temperature and invokes
  Type: unsigned	emergency shutdown functionality when exceeding this
  Size: one cell	temperature.

- off-temperature:	This value indicates the temperature to disable emergency
  Type: unsigned	shutdown.
  Size: one cell

- status:		Should be "disabled" always.
  Type: string

- target_cpus:		This property indicates which CPU will be targeted for shutdown.
  Type: phandle

thermal-zones {
	emergency {
		polling-delay = <1000>;    /* milliseconds */
		on-temperature = <110000>; /* millicelsius */
		off-temperature = <95000>; /* millicelsius */
		target_cpus = <&a57_1>,
			      <&a57_2>,
			      <&a57_3>;
		status = "disabled";
	};
};
