This series is to get the N116BCA-EA1 panel working. Most of the
patches are simple, but on hardware I have in front of me the panel
sometimes doesn't come up. I'm still working with the hardware
manufacturer to get to the bottom of it, but I've got it working with
retries. Adding the retries doesn't seem like an insane thing to do
and makes some of the error handling more robust, so I've gone ahead
and included those patches here. Hopefully they look OK.
Changes in v2:
- Set the "unprepared_time" so if we retry we give the proper delay.
- ("drm/panel-simple: Don't wait longer for HPD...") new for v2.
- ("drm/panel-simple: Retry if we timeout waiting for HPD") new for v2.
- ("dt-bindings: dt-bindings: display: simple: Add N116BCA-EA1") new for v2.
- ("drm/panel-simple: Add N116BCA-EA1") new for v2.

A quick "it's still in my queue" would be much appreciated! :-) If I don't hear anything then I guess next week I'll see if I can find other ways to poke folks or find a different route to land this series. Thanks! -Doug
