I've made it a custom to mention which board a panel is used on in the
commit message and I've requested others to do the same. The idea was
that it would give some kind of indication where to find the hardware if
somebody wanted to test or look at for reference.

This is missing device tree binding documentation.

Can you please name this according to the model for consistency with
other panels?

This needs to be the physical dimension in mm.

There's now also a new field called .bpc which contains the number of
bits per color (usually 6 or 8). Can you provide that as well? According
to the datasheet you linked to it should be 6.

From the commit message this panel is from AU Optronics, so it should
use the auo vendor prefix.
