[RFC PATCH 0/6] arm64: dts: qcom: Introduce AIM500 platform device tree

From: Jingyi Wang
Date: Mon Feb 05 2024 - 06:58:45 EST


Add the device tree for the AIM500 AIoT board along with usb, regulators,
serial and PCIe found in this board.

AIM500 Series is a highly optimized family of modules designed to support
AIoT and Generative AI applications which is based on SM8650P soc with
addtional functions like PMIC and bluetooth. And AIM500 AIoT is mounted
onto Qualcomm AIoT carrier board to support verification, evaluation and
development.

This patch series has some open discussion topics depend on [1], including:
1. memory map will have a large reserved region for firmware related,
since currently firmware features are still in developing and easily to
be changed.
2. vph_pwr was open whether it should be put in som.dtsi, or board.dts. we
can see vph_pwr may have different design and implementation from
different boards design, while vph_pwr needed to be one of the som input,
and then the vph_pwr is used inside som to different pmics input. So we
proposed have the definition in som.dtsi, and have it's own implementation
in board.dts.
3. board compatible like aim300-aiot was open whether can be added or not.
We added currently since it will fail dt binding check if not.

And we got following error while doing dtb check:
sm8650p-aim500-aiot.dtb: usb@a6f8800: interrupt-names: ['hs_phy_irq', 'ss_phy_irq', 'dm_hs_phy_irq', 'dp_hs_phy_irq'] is too short
Which should be caused by missing intertupt name "pwr_event" in sm8650.dtsi

Jingyi Wang (6):
dt-bindings: arm: qcom: Document sm8650p soc and AIM500 AIoT board
dt-bindings: arm: qcom,ids: Add SoC ID for SM8650P
soc: qcom: socinfo: Add SM8650P SoC ID table entry
arm64: dts: qcom: sm8650p: introduce sm8650p dtsi
arm64: dts: qcom: add base AIM500 dtsi
arm64: dts: qcom: add AIM500 AIoT
