This chip can be found in 96boards RB3 platform [1] commonly called DB845c. [1]: https://www.96boards.org/product/rb3-platform/ Changes in v6: - Drop msm/dsi patch as we need to get more bridges fixed before we add that - Bring back support for DRM_BRIDGE_ATTACH_NO_CONNECTOR not set, now driver supports both - Fix nits found by Sam Changes in v5: - make symbol static, reported by kbuild-bot Changes in v4: - Add msm/dsi patch to create connector and support DRM_BRIDGE_ATTACH_NO_CONNECTOR - Fix comments provided by Sam Changes in v3: - fix kbuild reported error - rebase on v5.8-rc1 Changes in v2: - Add acks by Rob - Fix comments reported by Emil and rename the file to lontium-lt9611.c - Fix comments reported by Laurent on binding and driver - Add HDMI audio support Vinod Koul (3): dt-bindings: vendor-prefixes: Add Lontium vendor prefix dt-bindings: display: bridge: Add documentation for LT9611 drm/bridge: Introduce LT9611 DSI to HDMI bridge .../display/bridge/lontium,lt9611.yaml | 176 +++ .../devicetree/bindings/vendor-prefixes.yaml | 2 + drivers/gpu/drm/bridge/Kconfig | 13 + drivers/gpu/drm/bridge/Makefile | 1 + drivers/gpu/drm/bridge/lontium-lt9611.c | 1229 +++++++++++++++++ 5 files changed, 1421 insertions(+) create mode 100644 Documentation/devicetree/bindings/display/bridge/lontium,lt9611.yaml create mode 100644 drivers/gpu/drm/bridge/lontium-lt9611.c
