My hardware is: LVDS IP <----------> LVDS to RGB bridge <------------> Panel While there is a simple "RGB to LVDS" bridge driver, there is none doing the work the other way around. In my case, the bridge has a reset pin. As until now there is no way to represent the "LVDS to RGB" bridge and because the bindings already document such reset pin, I decided to add support for it in the simple panel driver.
