[PATCH 4/4] arm64: dts: qcom: add SA8540P and ADP

Bjorn Andersson
2022-06-08T00:55:59Z

Introduce the Qualcomm SA8540P automotive platform and the SA8295P ADP
development board.

The SA8540P and SC8280XP are fairly similar, so the SA8540P is built
ontop of the SC8280XP dtsi to reduce duplication. As more advanced
features are integrated this might be re-evaluated.

This initial contribution supports SMP, CPUFreq, cluster idle, UFS, RPMh
regulators, debug UART, PMICs, remoteprocs (NSPs crashes shortly after
booting) and USB.

The SA8295P ADP contains four PM8450 PMICs, which according to their
revid are compatible with PM8150. They are defined within the ADP for
now, to avoid creating additional .dtsi files for PM8150 with just
addresses changed - and to allow using the labels from the schematics.
