Also, please try to stick to the "drm/panel: " prefix for panel patches (and "drm/panel: simple: " for panel-simple), which makes it easier for me to spot these patches in patchwork. Both of the above aren't blockers, so applied to drm-misc-next. Thanks, Thierry

This is news to me. At least in simple-panel land, I've always only split out additions of new vendor prefixes and kept the bindings together with the driver. I'll change that in the future if you prefer otherwise. > Also, please try > to stick to the "drm/panel: " prefix for panel patches (and "drm/panel: > simple: " for panel-simple), which makes it easier for me to spot these > patches in patchwork. Yeah, sorry about that. > Both of the above aren't blockers, so applied to drm-misc-next.

I don't mind too much either way, but I've seen Rob say he prefers separate patches. I guess ultimately that makes it easier to move the DT bindings outside of the kernel tree, but maybe there are other reasons, too. Rob, care to educate us? Thierry
