Subject: drm/panel: simple: Add bits-per-color support
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0208d51112b65e27490bc21ab6872358903f7d61;p=linux-beck.git

drm/panel: simple: Add bits-per-color support

The bits-per-color is provided by the EDID normally, but if we're using
panels, we need to store it somewhere. So we add a field to the panel
descriptor for it.
