[PATCH 0/2] Add support for PIXPAPER 4.26 monochrome e-ink panel

[LiangCheng Wang]

This patch series adds support for the Mayqueen Pixpaper 4.26
monochrome e-ink display panel, controlled via SPI.

The series includes:
- Device tree binding updates for the Pixpaper 4.26 panel
- A DRM tiny driver implementation for the Pixpaper 4.26 panel
- A MAINTAINERS update for the Pixpaper DRM drivers and binding

The panel supports 800x480 resolution with XRGB8888 framebuffer
input and uses SPI, along with GPIO lines for reset, busy, and
data/command control.

The driver has been tested on:
- Raspberry Pi 5
with Linux kernel 7.1.0-rc1.

Feedback is welcome.
