-* 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>;
- };
- ...
- };
