-* 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.
