I'd assume you don't have a datasheet here and that the timings are a
bit of a guess. It's nice if you put that in the commit message, but I
won't block it. Ideally you could reply here and let me know if you
referred to a datasheet or just made a guess about the timings so if
the question ever comes up later we can find the conversation based on
the Link: tag...

I assume this is just based on copy-paste from the lines around this. Jasper made this patch, but I assume he doesn't have any docs like that.

I briefly searched for the panel identifier some days ago and didn't directly stumble upon a datasheet.

Regards
Luca
