* 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.

|

...
|
||||
pvtctl: pvtctl {
|
