Subject: [PATCH 00/11] Updates to sc8280xp-pmic

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

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.

Thanks,
Mani
