Subject: [PATCH 0/3] Add support for Mayqueen Pixpaper e-ink panel

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

The series includes:
- A new vendor-prefix entry for "mayqueen"
- Device tree binding documentation for the Pixpaper panel
- A DRM tiny driver implementation for the Pixpaper panel
- A MAINTAINERS entry for the Pixpaper DRM driver and binding

The panel supports 122x250 resolution with XRGB8888 format and uses SPI,
along with GPIO lines for reset, busy, and data/command control.

The driver has been tested on:
- Raspberry Pi 2 Model B
with Linux kernel 6.16.

Feedback is welcome.

Best regards,  
LiangCheng Wang
