Analogix 7625 can be used in systems to switch the DP traffic between two downstreams, which can be USB Type-C DisplayPort alternate mode lane or regular DisplayPort output ports. Update the binding to accommodate this usage by introducing a data-lanes and a mode-switch property on endpoints. Also include the link to the product brief in the bindings. Signed-off-by: Pin-yen Lin <treapking@chromium.org> --- Changes in v8: - Updated anx7625 bindings for data-lane property - Fixed the subject prefix Changes in v7: - Fixed issues reported by dt_binding_check - Updated the schema and the example dts for data-lanes. - Changed to generic naming for the example dts node. Changes in v6: - Remove switches node and use endpoints and data-lanes property to describe the connections. .../display/bridge/analogix,anx7625.yaml | 99 ++++++++++++++++++- 1 file changed, 96 insertions(+), 3 deletions(-)
