[PATCH 0/3] arm64: dts: qcom: hamoa-crd: Introduce thermistor-based CPU throttling

[Bjorn Andersson]

The Hamoa CRD has multiple thermistors throughout the board to allow
measuring the temperature across different parts of the system. In line
with other platforms these are wired to the PMIC ADC and thermal monitor
blocks.

While "limits" hardware management provides rapid throttling of the
CPU cores, software needs to throttle the system e.g. during prolonged
CPU usage. Wire up the 7 thermistors found in the CRD as thermal zones
and throttle the CPU based on the "keyboard hotspot" thermistor.

The same mechanism is used on other Hamoa-based boards, but the
thermistor configuration and mapping is board-specific. As such, these
settings goes into the CRD dts. It's plausible that it could be shared
with the Purwa CRD, but this hasn't been confirmed.
