Re: [PATCH v3 2/2] drm/tiny: add support for PIXPAPER 4.26 monochrome e-ink panel

[LiangCheng Wang]

Hi Devarsh, Thomas,

Sorry to come back to this thread after a quiet spell, and apologies in
advance if I have missed something obvious.

Devarsh, the three fixes from my July testing on the PIXPAPER 4.26m are
still available:

  https://lore.kernel.org/all/20260731-ssd16xx-pixpaper-rpi5-v1-0-18ffc0dbf59a@xxxxxxxxx/

I am happy to rebase them, reshape them into whatever form fits your
series best, or retest on a newer kernel - whatever is most convenient
for you. There is no hurry at all from my side; please just let me know
if anything would be useful, and thank you again for making room for the
panel in your work.

Thomas, may I ask your advice on how best to handle the panel support in
the meantime? The PIXPAPER 4.26m is the only SSD16xx hardware I have, so
everything I can contribute is limited to this one panel, and its support
has been on hold since June waiting for the shared driver.

I wondered whether it might be acceptable to merge the standalone
PIXPAPER driver as an interim step, on the understanding that I convert
the panel over to ssd16xx and remove the standalone driver once the
shared driver lands. I realise that is not ideal, and I may well be
missing a better option - if you would prefer to wait for the shared
driver, I am perfectly happy to do that instead. I would rather follow
your judgement than guess.

Thank you both for the review time so far.

Regards,
LiangCheng
