Subject: [PATCH] Revert "arm64: dts: qcom: sm8250: switch UFS QMP PHY to new style of bindings"
Date: Thu,  3 Oct 2024 20:05:32 +0530	[thread overview]
Message-ID: <20241003143532.108444-1-sumit.semwal@linaro.org> (raw)

This reverts commit cf9c7b34b90b622254b236a9a43737b6059a1c14.

This commit breaks UFS on RB5 in the 6.1 LTS kernels. The original patch
author suggests that this is not a stable kernel patch, hence reverting
it.

This was reported during testing with 6.1.103 / 5.15.165 LTS kernels
merged in the respective Android Common Kernel branches.
