Subject: [PATCH] clk: qcom: dispcc-sc8280xp: Don't park mdp_clk_src at registration time
Date: Tue,  3 Mar 2026 23:01:51 +0800	[thread overview]
Message-ID: <20260303150152.90685-1-mitltlatltl@gmail.com> (raw)

Parking disp{0,1}_cc_mdss_mdp_clk_src clk broke simplefb on HUAWEI
Gaokun3, the image will stuck at grey for seconds until msm takes
over framebuffer. Use clk_rcg2_shared_no_init_park_ops to skip it.
