[PATCH] arm64: dts: qcom: x1e80100: Describe the full 'link' region of DP hosts
Posted by Konrad Dybcio 4 months ago

The regions are larger than currently described. Rather inconveniently,
some control registers, including some related to USB4, are in that
left-out chunk.

Extend it to cover the entire region, as per the hw specification.

Fixes: 1940c25eaa63 ("arm64: dts: qcom: x1e80100: Add display nodes")
