[1/4] drm/msm/dsi/phy: Protect PHY_CMN_CLK_CFG0 updated from driver side https://gitlab.freedesktop.org/drm/msm/-/commit/588257897058 [2/4] drm/msm/dsi/phy: Protect PHY_CMN_CLK_CFG1 against clock driver https://gitlab.freedesktop.org/drm/msm/-/commit/5a97bc924ae0 [3/4] drm/msm/dsi/phy: Do not overwite PHY_CMN_CLK_CFG1 when choosing bitclk source https://gitlab.freedesktop.org/drm/msm/-/commit/73f69c6be2a9 Best regards,
Changes in v3: - Define bitfields in patches 1-3, so move there parts from patch #4 - Use FIELD_GET - Keep separate cached->bit_clk_div and pix_clk_div - I think this implements entire feedback from Dmitry - Link to v2: https://lore.kernel.org/r/20250203-drm-msm-phy-pll-cfg-reg-v2-0-862b136c5d22@linaro.org Changes in v2: - Add Fixes tag - New patch #4 - Link to v1: https://lore.kernel.org/r/20250131-drm-msm-phy-pll-cfg-reg-v1-0-3b99efeb2e8d@linaro.org Calling these improvements, not fixes, because I don't think we ever hit actual concurrency issue. Although if we ever hit it, it would be very tricky to debug and find the cause.
