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@...40000 {
- 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>;
