This is a note to let you know that I've just added the patch titled arm64: dts: qcom: msm8916: Drop MSS fallback compatible to the 6.1-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: arm64-dts-qcom-msm8916-drop-mss-fallback-compatible.patch and it can be found in the queue-6.1 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 420b6d5800eba7530852d04a1135342326b2d879 Author: Stephan Gerhold <stephan.gerhold@xxxxxxxxxxxxxxx> Date: Mon Jul 18 16:03:40 2022 +0200 arm64: dts: qcom: msm8916: Drop MSS fallback compatible [ Upstream commit ff02ac621634e82c0c34d02a79d402ae700cdfd0 ] MSM8916 was originally using the "qcom,q6v5-pil" compatible for the MSS remoteproc. Later it was decided to use SoC-specific compatibles instead, so "qcom,msm8916-mss-pil" is now the preferred compatible. Commit 60a05ed059a0 ("arm64: dts: qcom: msm8916: Add MSM8916-specific compatibles to SCM/MSS") updated the MSM8916 device tree to make use of the new compatible but still kept the old "qcom,q6v5-pil" as fallback. This is inconsistent with other SoCs and conflicts with the description in the binding documentation (which says that only one compatible should be present). Also, it has no functional advantage since older kernels could not handle this DT anyway (e.g. "power-domains" in the MSS node is only supported by kernels that also support "qcom,msm8916-mss-pil"). Make this consistent with other SoCs by using only the "qcom,msm8916-mss-pil" compatible.
