It is still wrong. You have slash there. Sorry, I didn't even notice that.

ITE IT6505 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. Signed-off-by: Pin-yen Lin <treapking@chromium.org> --- Changes in v8: - Updated bindings for data-lanes property - Fixed 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. .../bindings/display/bridge/ite,it6505.yaml | 93 ++++++++++++++++--- 1 file changed, 82 insertions(+), 11 deletions(-)
