The timing values for dw-dsi are often dependent on the used display and according to Philippe Cornu will most likely also depend on the used phy technology in the soc-specific implementation. To solve this and allow specific implementations to define them as needed add a new get_timing callback to phy_ops and call this from the dphy_timing function to retrieve the necessary values for the specific mode. Right now this handles the hs2lp + lp2hs where Rockchip SoCs need handling according to the phy speed, while STM seems to be ok with static values. changes in v5: - rebase on 5.5-rc1 - merge into px30 dsi series to prevent ordering conflicts changes in v4: - rebase to make it directly fit on top of drm-misc-next after all changes in v3: - check existence of phy_ops->get_timing in __dw_mipi_dsi_probe() - emit actual error when get_timing() call fails - add tags from Philippe and Yannick changes in v2: - add driver-specific handling, don't force all bridge users to use the same timings, as suggested by Philippe Suggested-by: Philippe Cornu <philippe.cornu@st.com> Signed-off-by: Heiko Stuebner <heiko.stuebner@theobroma-systems.com> Reviewed-by: Philippe Cornu <philippe.cornu@st.com> Tested-by: Yannick Fertre <yannick.fertre@st.com> Reviewed-by: Neil Armstrong <narmstrong@baylibre.com> Link: https://patchwork.freedesktop.org/patch/msgid/20191209143130.4553-2-heiko@sntech.de |
