Version 4: - bridge/synopsis/dw-mipi-dsi.c: Add panel-bridge support (-45 lines, but no so easy to do) and is_panel_bridge for a better clean up, add stm copyright/remove dpms_mode/remove drm_of.h/improve clk management/add mode_valid (thanks to comments of Archit Taneja), use "DesignWare" instead of "Designware (thanks to comments of Neil Armstrong) - bridge/synopsis/Kconfig: Remove help section to hide it in menuconfig (thanks to comments of Archit Taneja) - include/drm/bridge/dw_mipi_dsi.h: Remove drmP.h (thanks to comments of Archit Taneja) - bindings/display/bridge/dw_mipi_dsi.txt: Improve optional property explanations (thanks to comments of Neil Armstrong) - stm/ltdc.c: Add is_panel_bridge for a better clean up/remove drm_encoder_helper_add() (thanks to comments of Eric Anholt) - stm/dw_mipi_dsi-stm.c: remove math64.h/use DRM_WARN/remove warnings (thanks to comments of Archit Taneja), minor alignment fix (thanks to comments of Neil Armstrong) - bindings/display/st,stm32-ltdc.txt: use graph binding in the example/improve ports usage doc (thanks to comments of Rob Herring), use "DSI" instead of "dsi" where relevant (thanks to comments of Neil Armstrong)
Version 3: - stm/ltdc: Use panel-bridge (-170 lines), thanks to comments of Eric Anholt, Boris Brezillon, Archit Taneja & Andrzej Hajda. - Synopsys dsi: Add dw_mipi_dsi.h (forgotten in v2), thanks to comments of Neil Armstrong. - Synopsys dsi/dw-mipi-dsi.c: add dw_mipi_dsi_dphy_init() & dw_mipi_dsi_dphy_enable() to better manage DW phy-dedicated regs, remove dw_mipi_dsi_mode enum, remove stm32 patch for lpm, remove pllref (manage in the vendor phy) thanks to comments of Archit Taneja. Add mode_flags to phy parameters to better adjust lane mbps according to dsi burst and non burst modes todos in caps. - stm/dw_mipi_dsi-stm.c: Add pllref management. - dt-bindings/display/stm: Split dt-bindings patch in two (parent node removal/ dsi), add required nodes (port & panel/bridge), updates thanks to comments of Rob Herring. - dt-bindings/display/Synopsys dsi: remove port as part of the vendor documentation, add panel/bridge node, update dt-bindings thanks to comments of Rob Herring. - Add more people from Hisilicon & Rockchip.
Version 2: - Add a generic Synopsys DesignWare MIPI DSI bridge driver following comments from Neil Armstrong & Archit Taneja. - Use drm_of_find_panel_or_bridge() thanks to Eric Anholt comments - Update dt-bindings thanks to Rob Herring comments
Version 1: - Initial commit
The purpose of this set of patches is to add the mipi dsi host driver to the stm32 family.
This mipi dsi host driver is based on the Rockchip version of the Synopsys Designware mipi dsi driver (rockchip/dw-mipi-dsi.c) modified for the stm32 family: - replace Rockchip digital & phy specific extensions with stm32's ones. - add a bridge
