I've applied this, though I had to make a few modifications. First, I
added a commit message. Commits should always have one.
Also, please send DT bindings and driver changes as separate patches in
the future.
Device tree bindings should have a subject prefixed with any of these:
dt-bindings:
dt-bindings: display:
dt-bindings: display: panel:
Though the latter two are fairly long by themselves, so you don't have a
lot of room for the important bits.
Please also prefix the subject of panel driver patches with a:
drm/panel:
Which makes it easier to identify relevant patches among loads and loads
of other email.

Looks like these are actually sorted correctly in your patch. However,
when applying these got added after the Toshiba panel that was recently
added, so I resorted again.
