* UniPhier Thermal bindings

This describes the devicetree bindings for thermal monitor supported by

PVT(Process, Voltage and Temperature) monitoring unit implemented on Socionext

UniPhier SoCs.

Required properties:

- compatible :

  - "socionext,uniphier-pxs2-thermal" : For UniPhier PXs2 SoC

  - "socionext,uniphier-ld20-thermal" : For UniPhier LD20 SoC

  - "socionext,uniphier-pxs3-thermal" : For UniPhier PXs3 SoC

- interrupts : IRQ for the temperature alarm

- #thermal-sensor-cells : Should be 0. See ./thermal.txt for details.

Optional properties:

- socionext,tmod-calibration: A pair of calibrated values referred from PVT,

                              in case that the values aren't set on SoC,

                              like a reference board.

Example:

	sysctrl@61840000 {

		compatible = "socionext,uniphier-ld20-sysctrl",

			     "simple-mfd", "syscon";

		reg = <0x61840000 0x10000>;

		...

		pvtctl: pvtctl {

			compatible = "socionext,uniphier-ld20-thermal";

			interrupts = <0 3 1>;

			#thermal-sensor-cells = <0>;

		};

		...

	};

	thermal-zones {

		cpu_thermal {

			polling-delay-passive = <250>;	/* 250ms */

			polling-delay = <1000>;		/* 1000ms */

			thermal-sensors = <&pvtctl>;

			trips {

				cpu_crit: cpu_crit {

					temperature = <110000>;	/* 110C */

					hysteresis = <2000>;

					type = "critical";

				};

				cpu_alert: cpu_alert {

					temperature = <100000>;	/* 100C */

					hysteresis = <2000>;

					type = "passive";

				};

			};

			cooling-maps {

				map0 {

					trip = <&cpu_alert>;

					cooling-device = <&cpu0 (-1) (-1)>;

				};

				map1 {

					trip = <&cpu_alert>;

					cooling-device = <&cpu2 (-1) (-1)>;

				};

			};
