This is not sorted properly. 0x0af2 does not belong between 0x0b1e and 0x0b34.
...I could fix that when applying, but I also have a question: do you
have access to the datasheet of this panel, or are you just guessing
the right timing by looking at the nearby panels? I assume you have
this panel yourself for testing and confirm it seems to work OK.
It's fine if you don't have the datasheet and are making guesses,
since acquiring the datasheet is really hard for end-users. ...but in
that case, I like to at least document that fact in the commit message
so if someone later comes along and proposes different timings (and
they have the datasheet) then we can figure out how to proceed. :-)
