Changes since v1:
- Add maxItems to "socionext,tmod-calibration" property
- Fix indents in examples

-* 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)>;
-				};
-			};
