From: Petr Hodina <[email protected]>Add CLK_OPS_PARENT_ENABLE to MDSS pixel clock sources to ensure parent clocks are enabled during clock operations, preventing potential stability issues during display configuration. Fixes: 81351776c9fb ("clk: qcom: Add display clock controller driver for SDM845") Signed-off-by: Petr Hodina <[email protected]> --- We are currently running the latest linux-next snapshots (next-202511* and next-202512*) and have encountered random freezes and crashes on the Pixel 3, as well as crash dumps on the OnePlus 6 and 6T. This commit fixes the stability issue. I've checked other SDM dispcc files and they also contain this configuration. For safety I also set the configuration for `disp_cc_mdss_pclk1_clk_src` though it should be sufficient only for `disp_cc_mdss_pclk0_clk_src`. Kind regards, Petr --- Changes in v2: - Remove commits from v1 and introduce proper fix. - Link to v1: https://lore.kernel.org/r/[email protected] --- drivers/clk/qcom/dispcc-sdm845.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-)
