Subject: [PATCH v5 0/2] Add lontium lt8713sx bridge driver
Date: Tue, 03 Mar 2026 22:13:34 +0530 [thread overview]
Message-ID: <20260303-lt8713sx-bridge-driver-v5-0-6cc2a855aafa@oss.qualcomm.com> (raw)
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.

Changes in v5:
- Commit msg changed a bit
- Added Author Maintainer after confirmation from Lontium
- Link to v4: https://lore.kernel.org/r/20260224-lt8713sx-bridge-driver-v4-0-b5603f5458d8@oss.qualcomm.com
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-v3-0-9169fbef0e5b@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-v2-0-25ad49280a11@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.
