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
