[PATCH v2 0/3] drm/tiny: Add MAYQUEEN PIXPAPER e-ink panel support

[LiangCheng Wang <zaq14760@gmail.com>]

This series adds support for the MAYQUEEN PIXPAPER e-ink panel
(122x250 pixels, SPI-controlled) to the tiny drm subsystem.

Patches (must be applied in order due to dependencies):
Patch 1/3: Adds 'mayqueen' vendor prefix.
Patch 2/3: Implements PIXPAPER tiny drm driver.
Patch 3/3: Adds PIXPAPER device tree bindings.

Tested on PIXPAPER hardware with linux-5.10.y-cip,
verifying display initialization and refresh.
All patches pass checkpatch.pl.
