[PATCH v2 1/4] arm64: dts: qcom: sc7280-chrome-common: disable Venus

From: Dmitry Baryshkov <hidden>
Date: 2026-01-26 02:09:51
Also in: linux-arm-msm, linux-media, lkml
Subsystem: arm/qualcomm chromebook support, arm/qualcomm mailing list, arm/qualcomm support, the rest · Maintainers: Bjorn Andersson, Konrad Dybcio, Linus Torvalds

Iris driver doesn't support non-PAS/TZ setup for setting up the Iris
core. It's expected that the ABI that is going to be used in a long-term
would be different from the defined venus-firmware subnode.

Granted that the SC7280 Chromebooks were cancelled before reaching wide
audience and granted the feature ABI changes, drop venus configuration
for SC7280 ChromeOS devices.
