[PATCH v2 0/2] drm/tiny: Ensure DT compatibles have SPI device IDs

[Mark Brown]

Currently autoloading for SPI devices does not use the DT ID table, it uses
SPI modalises. Supporting OF modalises is going to be difficult if not
impractical, an attempt was made but has been reverted, so this series
adds SPI IDs where they aren't provided for a given modalias.

v2:
 - Rebase onto v5.17-rc1.

Mark Brown (2):
  drm/ili9486: Add SPI ID table
  drm/st7735r: Add SPI ID table

[PATCH v2 1/2] drm/ili9486: Add SPI ID table

[Mark Brown]

Currently autoloading for SPI devices does not use the DT ID table, it uses
SPI modalises. Supporting OF modalises is going to be difficult if not
impractical, an attempt was made but has been reverted, so ensure that
module autoloading works for this driver by ensuring that there are SPI IDs
for all OF IDs.
