Subject[PATCH 03/10] arm64: dts: qcom: sc8280xp: add missing PCIe minimum OPP
Date
Add the missing PCIe CX performance level votes to avoid relying on
other drivers (e.g. USB or UFS) to maintain the nominal performance
level required for Gen3 speeds.

Fixes: 813e83157001 ("arm64: dts: qcom: sc8280xp/sa8540p: add PCIe2-4 nodes")
Cc: stable@vger.kernel.org # 6.2
