Add a reference to the relevant reset. It fixes display init issue appeared in Linux v6.17: without reset device boots into black screen and you need to turn display off/on to "fix" it. Also sometimes it can boot into solid blue color with these messages in kernel log: hw recovery is not complete for ctl:2 [drm:dpu_encoder_phys_vid_prepare_for_kickoff:569] [dpu error]enc33 intf1 ctl 2 reset failure: -22 [drm:dpu_encoder_frame_done_timeout:2727] [dpu error]enc33 frame done timeout Fixes: 0e789b491ba0 ("pmdomain: core: Leave powered-on genpds on until sync_state") Cc: stable@vger.kernel.org # 6.17 Signed-off-by: Alexey Minnekhanov Reviewed-by: Dmitry Baryshkov Link: https://lore.kernel.org/r/20251116-sdm660-mdss-reset-v2-3-6219bec0a97f@postmarketos.org Signed-off-by: Bjorn Andersson Signed-off-by: Sasha Levin --- arch/arm64/boot/dts/qcom/sdm630.dtsi | 1 + 1 file changed, 1 insertion(+) diff --git a/arch/arm64/boot/dts/qcom/sdm630.dtsi b/arch/arm64/boot/dts/qcom/sdm630.dtsi index b383e480a394d..876a6871745cf 100644 --- a/arch/arm64/boot/dts/qcom/sdm630.dtsi +++ b/arch/arm64/boot/dts/qcom/sdm630.dtsi @@ -1563,6 +1563,7 @@ mdss: display-subsystem@c900000 { reg-names = "mdss_phys", "vbif_phys"; power-domains = <&mmcc MDSS_GDSC>; + resets = <&mmcc MDSS_BCR>; clocks = <&mmcc MDSS_AHB_CLK>, <&mmcc MDSS_AXI_CLK>, -- 2.51.0
