Few notes: - assign-clock-parents is a mandatory proprety according to the current dsi.txt description. - There is little point in duplicating this functionality with the ad-hoc implementation in the dsi code. On top of that come few minor cleanups for the DSI PHY drivers. I'd kindly ask to bring all dts changes also through the drm tree, so that there won't be any breakage of the functionality. The patchset was tested on RB3 (single DSI), RB5 (single DSI, two independent DSI, bonded DSI, two last configs require additional patches which do not concern the DSI timings code). Changes since v1: - add dt-bindings change - drop the patch removing msm_dsi_dphy_timing The following changes since commit e88bbc91849b2bf57683119c339e52916d34433f: Revert "drm/msm/mdp5: provide dynamic bandwidth management" (2021-06-23 14:06:20 -0700) are available in the Git repository at: https://git.linaro.org/people/dmitry.baryshkov/kernel.git dsi-phy-update for you to fetch changes up to a79d84d8eac721a7ebaf3cfc65b200077b1d6947: drm/msm/dsi: drop msm_dsi_phy_get_shared_timings (2021-07-10 00:02:18 +0300) ---------------------------------------------------------------- Dmitry Baryshkov (8): dt-bindings: display: msm: dsi-controller-main: restore assigned-clocks arm64: dts: qcom: sc7180: assign DSI clock source parents arm64: dts: qcom: sdm845: assign DSI clock source parents arm64: dts: qcom: sdm845-mtp: assign DSI clock source parents arm64: dts: qcom: sm8250: assign DSI clock source parents drm/msm/dsi: stop setting clock parents manually drm/msm/dsi: phy: use of_device_get_match_data drm/msm/dsi: drop msm_dsi_phy_get_shared_timings .../bindings/display/msm/dsi-controller-main.yaml | 17 ++++++++ arch/arm64/boot/dts/qcom/sc7180.dtsi | 3 ++ arch/arm64/boot/dts/qcom/sdm845-mtp.dts | 3 ++ arch/arm64/boot/dts/qcom/sdm845.dtsi | 6 +++ arch/arm64/boot/dts/qcom/sm8250.dtsi | 6 +++ drivers/gpu/drm/msm/dsi/dsi.h | 7 +-- drivers/gpu/drm/msm/dsi/dsi_host.c | 51 ---------------------- drivers/gpu/drm/msm/dsi/dsi_manager.c | 8 +--- drivers/gpu/drm/msm/dsi/phy/dsi_phy.c | 34 ++++----------- 9 files changed, 47 insertions(+), 88 deletions(-)
