Hello, this series touches the bindings and the driver handling endpoint properties for digital subdevices of the R-Car VIN driver. The first patch simply documents what are the endpoint properties supported at the moment, then the second one extends them with 'data-active'. As the VIN hardware allows to use HSYNC as data enable signal when the CLCKENB pin is left unconnected, the 'data-active' property presence determinates if HSYNC has to be used or not as data enable signal. As a consequence, when running with embedded synchronism, and there is not HSYNC signal, it becomes mandatory to specify 'data-active' polarity in DTS. To address this, all Gen-2 boards featuring a composite video input and running with embedded synchronization, now need that property to be specified in DTS. Before adding it, remove un-used properties as 'pclk-sample' and 'bus-width' from the Gen-2 bindings, as they are not parsed by the VIN driver and only confuse users. Niklas, as you already know I don't have any Gen2 board. Could you give this a spin on Koelsch if you like the series?
