This is a note to let you know that I've just added the patch titled arm64: dts: qcom: sdm845: Reserve LPASS clocks in gcc to the 5.4-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-sdm845-reserve-lpass-clocks-in-gcc.patch and it can be found in the queue-5.4 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit f8f1165dda9be1b14eb7e408ad41bc053afa0ad9 Author: Bjorn Andersson <bjorn.andersson@xxxxxxxxxx> Date: Mon Dec 21 16:11:03 2020 -0800 arm64: dts: qcom: sdm845: Reserve LPASS clocks in gcc [ Upstream commit 93f2a11580a9732c1d90f9e01a7e9facc825658f ] The GCC_LPASS_Q6_AXI_CLK and GCC_LPASS_SWAY_CLK clocks may not be touched on a typical UEFI based SDM845 device, but when the kernel is built with CONFIG_SDM_LPASSCC_845 this happens, unless they are marked as protected-clocks in the DT. This was done for the MTP and the Pocophone, but not for DB845c and the Lenovo Yoga C630 - causing these to fail to boot if the LPASS clock controller is enabled (which it typically isn't).
