Changes from v12 for dp driver: dt-binding: - Fix build error. embedded dp drivers: - Revise Kconfig to let this driver independent. - Drop some unused/redundant drivers. - Move some features to patches of external dp and audio. - Refine format error control flow. - Add error control of write register functions. - Use mtk sip common definitions. Changes from v11 for dp driver: dt-binding: - Use data-lanes to determine the max supported lane numbers. - Add mhz to max-linkrate to show the units. embedded dp drivers: - Modify Makefile. - Drop some unused/redundant drivers. - Move some features to patches of external dp and audio. - Modify break condition of training loop to control cr/eq fail. - Replace some function/definition with ones of common drm drivers. - Remove dp_lock mutex because it's only locked in power_on/off. - Add drm_dp_aux_(un)register in mtk_dp_bridge_(de)attach. Changes from v10 for dp driver: - Drop return value for write registers to make code more clear. - Refine training state. - Add property for dt-binding. - Add new bug fix patches for audio and suspend. - Rebase to v5.19-rc1. Changes from v9: - The DP-Phy is back to being a child device of the DP driver (as in v8) - hot plug detection has been added back to Embedded Display Port... as after discussing with mediatek experts, this is needed eventhough the Embedded Display port is not un-pluggable - rebased on linux-next - simplified/split train_handler function, as suggested by Rex - added comments on the sleep/delays present in the code - removed previous patch introducing retries when receiving AUX_DEFER as this is already handled in the dp_aux framework - added max-lane and max-linkrate device tree u8 properties instead of hardcoded #defines Older revisions: RFC - https://lore.kernel.org/linux-mediatek/20210816192523.1739365-1-msp@baylibre.com/ v1 - https://lore.kernel.org/linux-mediatek/20210906193529.718845-1-msp@baylibre.com/ v2 - https://lore.kernel.org/linux-mediatek/20210920084424.231825-1-msp@baylibre.com/ v3 - https://lore.kernel.org/linux-mediatek/20211001094443.2770169-1-msp@baylibre.com/ v4 - https://lore.kernel.org/linux-mediatek/20211011094624.3416029-1-msp@baylibre.com/ v5 - https://lore.kernel.org/all/20211021092707.3562523-1-msp@baylibre.com/ v6 - https://lore.kernel.org/linux-mediatek/20211110130623.20553-1-granquet@baylibre.com/ v7 - https://lore.kernel.org/linux-mediatek/20211217150854.2081-1-granquet@baylibre.com/ v8 - https://lore.kernel.org/linux-mediatek/20220218145437.18563-1-granquet@baylibre.com/ v9 - https://lore.kernel.org/all/20220327223927.20848-1-granquet@baylibre.com/ v10 - https://lore.kernel.org/all/20220523104758.29531-1-granquet@baylibre.com/ v11 - https://lore.kernel.org/r/20220610105522.13449-1-rex-bc.chen@mediatek.com v12 - https://lore.kernel.org/all/20220627080341.5087-1-rex-bc.chen@mediatek.com/ v13 - https://lore.kernel.org/all/20220701062808.18596-1-rex-bc.chen@mediatek.com/ Bo-Chen Chen (2): drm/mediatek: set monitor to DP_SET_POWER_D3 to avoid garbage drm/mediatek: Use cached audio config when changing resolution Guillaume Ranquet (4): drm/edid: Convert cea_sad helper struct to kernelDoc drm/edid: Add cea_sad helpers for freq/length drm/mediatek: Add MT8195 External DisplayPort support drm/mediatek: DP audio support for MT8195 Jitao Shi (1): drm/mediatek: add hpd debounce Markus Schneider-Pargmann (3): dt-bindings: mediatek,dp: Add Display Port binding video/hdmi: Add audio_infoframe packing for DP drm/mediatek: Add MT8195 Embedded DisplayPort driver .../display/mediatek/mediatek,dp.yaml | 115 + drivers/gpu/drm/drm_edid.c | 73 + drivers/gpu/drm/mediatek/Kconfig | 9 + drivers/gpu/drm/mediatek/Makefile | 2 + drivers/gpu/drm/mediatek/mtk_dp.c | 2951 +++++++++++++++++ drivers/gpu/drm/mediatek/mtk_dp_reg.h | 545 +++ drivers/video/hdmi.c | 82 +- include/drm/display/drm_dp.h | 2 + include/drm/drm_edid.h | 26 +- include/linux/hdmi.h | 7 +- 10 files changed, 3789 insertions(+), 23 deletions(-) create mode 100644 Documentation/devicetree/bindings/display/mediatek/mediatek,dp.yaml create mode 100644 drivers/gpu/drm/mediatek/mtk_dp.c create mode 100644 drivers/gpu/drm/mediatek/mtk_dp_reg.h
