Hello,
This series adds below updates to sc8280xp-pmics:
PM8280_{1/2}:
- Temp alarm
- Thermal zones
- VADC channels
- ADC_TM5 channels
PMK8280:
- ADC7 block
- VADC channels
- TM5 block
PMR735A:
- VADC channels
Also adds the thermal zone support to Lenovo X13s based on the thermistor
SYS_THERM6 that provides the laptop skin temperature.
The sc8280xp-pmics is based on the new PMIC7 architecture. In this, all the
ADC/TM5 measurements are collected by the primary PMIC PMK8280 from other
slave PMICs PM8280_{1/2}, PMR735A using the Programmable Boot Sequence (PBS)
and exposed them over the individual channels.
PMK8280 uses the Slave ID (SID) for identifying each slave PMICs in a system.
This ID is not static for each PMIC but rather set for each platform by the
hardware designers. So this series allows the configurable SID by modifying the
binding to accept SID values instead of hardcoding them.
This series is tested on Lenovo X13s laptop by monitoring the temperature of
the 8 on-board thermistors through IIO interface. The thermal zone support is
validated by adding loads to the CPUs and making sure the skin temperature stays
below the threshold provided in DT.
Thanks,
Mani
Changes in v3:
* Used thermistor index in node names for VADC channels. This is required by IIO
* Collected reviews
* Rearranged the dt properties (Konrad)
Changes in v2:
* Fixed issues reported by Krzysztof and "make dtbs_check"
* Collected reviews from Krzysztof
* Added the Lenovo X13s thermal zone patch
