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. --- Changes in v2: - Reordered patches so that DT bindings come before the driver (suggested by Rob Herring) - Fixed sparse warning: removed duplicate `.reset` initializer in `pixpaper_plane_funcs` - Fixed checkpatch issues reported by Media CI: - Removed unnecessary blank line before closing brace - Moved opening parentheses up to function call lines (e.g., `DRM_WARN(...)`) - Fixed alignment of conditionals - Fixed `dev_warn(` and `drm_universal_plane_init(` formatting - Thanks to Rob Herring for ack on vendor-prefix patch - Link to v1: https://lore.kernel.org/r/20250708-drm-v1-0-45055fdad...@gmail.com Thanks for the feedback!
