Hello there, A while ago I added support for the FS035VG158 panel to the kernel, with its use case being on a Allwinner T113 board. While troubleshooting some other issue (I will be posting about that this weekend) I found that I need to tell the panel controller to use a bit depth of 18-bit in order for the panel to work correctly. I plan to add another panel to the kernel that also requires setting the bit depth, but has more configurations than just 24, 18, 16, it also supports packing 18 of the bits together. How all of this is configured depends on how the board and panel are wired together, it can't be determined at runtime based on pixel formats or anything like that. It seems to me that this needs to be specified in the device tree. My question is: How would I represent this? A property like 'bit-depth'? 'color-mapping'? Or is there already some subsystem or convention designed for this? John.
