I chose to touch this driver just because it seems that this DPI color encoder fits the description of simple-bridge.yaml: -8<- description: | This binding supports transparent non-programmable bridges that don't require any configuration, with a single input and a single output. -8<- Anyway, if you think another driver is really needed and DT maintainers accept to document this DPI color encoder, I may try to write one. > > Maxime -- Regards, Liu Ying
