[0/3] drm/panel: Add MIPI DBI compatible SPI driver

Message

Hi,

This patchset adds a driver that will work with most MIPI DBI compatible
SPI panels out there.

It's a follow up on 'drm/tiny/st7735r: Match up with staging/fbtft
driver'[1] which aimed at making the st7735r driver work with all panels
adding DT properties.

Maxime gave[2] a good overview of the situation with these displays and
proposed to make a driver that works with all MIPI DBI compatible
controllers and use a firmware file to provide the controller setup for
a particular panel.

Noralf.
