input video data format.COLOR_RGB = 0, COLOR_YCBCR422 = 1, COLOR_YCBCR444 = 2I don't think DT is an appropriate place to set this. To my knowledge this depends on the display and/or mode, so I don't think hard-coding it here is the right thing to do.
Yeah, same question with my previous reply ;)
I don't have an answer for you, unfortunately. But like I said, hard-coding isn't going to work. What if, for example, you set this to a fixed value and then you connect a monitor that doesn't support the specific one you set?
You cited code from dw_hdmi.c earlier, it looks like it might be correct even though it doesn't cite a reference for why this was done. Perhaps someone on this thread, or someone involved with dw_hdmi can answer where that code came from.
