Hi! I naively thought that since there was support for both nxp,tda19988 (in the tda998x driver) and the atmel-hlcdc, things would be a smooth ride. But it wasn't, so I started looking around, and found some missing pieces in the tilcdc driver. A "stole" some things and made it work for my use case. During this, I found that the tda998x driver never sets the format in the connector display_info. Thus, the atmel-hlcdc driver fails to select output format. Since I had similar problems with ds90c185 lvds encoder I added patches to override the atmel-hlcdc output format via a DT property and things start to play together. Since this series superseeds the bridge series, I have included the leftover bindings patch for the ti,ds90c185 here. I also noticed that the driver date for atmel-hlcdc is bonkers, and added a patch for that. However, I don't know if the tilcdc driver is interfacing with the tda998x driver in a sane and modern way, and I don't know if I have missed any subtle point when I "stole" the code and componentized the atmel-hlcdc driver. I also have not tested how this behaves if I run with the components as modules (not targeting that). Anyway, this series solves some real issues for my HW.
