Subject: arm64: dts: qcom: sm8450: Throttle the GPU when overheating
X-Git-Tag: io_uring-6.11-20240722~96^2~8^2~65
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=4be0dd44c39b083148ae9d4c4a7ef6d64e6c0062;p=linux-block.git

arm64: dts: qcom: sm8450: Throttle the GPU when overheating

Add an 85C passive trip point to ensure the thermal framework takes
sufficient action to prevent reaching junction temperature and a
110C critical point to help avoid hw damage.

Remove the copypasta-from-downstream userspace governor entries while
at it.
