The lt8713sx is a Type-C/DP1.4 to Type-C/DP1.4/HDMI2.0 converter, with three configurable DP1.4/HDMI2.0/DP++ output interfaces and audio output interface.
This series provides bridge driver and dt bindings for lt8713sx. The driver is required for firmware upgrade and enabling the bridge chip. Signed-off-by: Vishnu Saini <[email protected]> --- Changes in v4: - Improved crc calculation, calculated on padded buffer instead of bit by bit. - Fixed brm bridge chain, using single drm_bridge as bridge chip itself will take care of providing all edp outputs from single input. - Used guard mutex where needed. - Link to v3: https://lore.kernel.org/r/20251228-lt8713sx-bridge-driver-v3-0-9169fbef0...@oss.qualcomm.com Changes in v3: - Used linux/sizes.h header for size definations. - Used linux/crc8.h for CRC calculation - Added Basic drm_bridge changes to support corresponding ports handeling in dt - Ran coccinelle, smatch and sparse checkpatch.pl tools to improve code quality. - Link to v2: https://lore.kernel.org/r/20251118-lt8713sx-bridge-driver-v2-0-25ad49280...@oss.qualcomm.com Changes in v2: - Addressed review comments from V1, majorly: - Fixed DCO chain. - Added supply in bindings. - Handeled deferred probe in lt8713sx driver probe. - Link to v1: https://lore.kernel.org/r/20251115-lt8713sx-bridge-driver-v1-0-bd5a1c1c7...@oss.qualcomm.com --- Vishnu Saini (2): dt-bindings: bridge: lt8713sx: Add bindings drm/bridge: add support for lontium lt8713sx bridge driver .../bindings/display/bridge/lontium,lt8713sx.yaml | 113 ++++ drivers/gpu/drm/bridge/Kconfig | 10 + drivers/gpu/drm/bridge/Makefile | 1 + drivers/gpu/drm/bridge/lontium-lt8713sx.c | 598 +++++++++++++++++++++ 4 files changed, 722 insertions(+) --- base-commit: de0d6e19d2ef33ba34be2467ffdf3595da5f5326 change-id: 20251115-lt8713sx-bridge-driver-32704455bc9a Best regards, -- Vishnu Saini <[email protected]>
