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

[LiangCheng Wang <zaq14760@gmail.com>]

Hi Thomas,

Thanks for the review, and no worries about the timing.

Before I spin a v4 for these comments, I'd like to confirm the overall
direction, since it affects whether this should remain a standalone driver
at all.

In parallel, Devarsh Thakkar is adding a generic Solomon SSD16xx e-paper
driver (panel-ssd16xx.c, currently v1 in review). The PIXPAPER 4.26 uses an
SSD1677, which is part of that family; Devarsh has said he will add SSD1677
support in the next revision (v2) of his series, after which this panel
could be supported there as a panel entry rather than as a separate driver.
That work isn't posted yet, but I had agreed that consolidating under
panel-ssd16xx.c is the better long-term direction.

I'd appreciate your guidance on how to proceed -- whether it is better to
keep iterating on this standalone driver, or to hold it and add the
PIXPAPER 4.26 panel to panel-ssd16xx.c once that driver supports SSD1677.
I'm happy to go whichever way you prefer.

Regards,
LiangCheng
