[PATCH v3 2/4] drm/msm/dsi/phy: Protect PHY_CMN_CLK_CFG1 against clock driver

2025-02-14 Thread Krzysztof Kozlowski
PHY_CMN_CLK_CFG1 register is updated by the PHY driver and by a mux clock from Common Clock Framework: devm_clk_hw_register_mux_parent_hws(). There could be a path leading to concurrent and conflicting updates between PHY driver and clock framework, e.g. changing the mux and enabling PLL clocks.
