Hi,
This patchset adds a driver that will work with most MIPI DBI compatible
SPI panels out there.
Maxime gave[1] 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.
Changes since version 3:
- There should only be two compatible (Maxime)
- s/panel-dbi-spi/panel-mipi-dbi-spi/in compatible
- Move driver to drm/tiny where the other drivers of its kind are located.
The driver module will not be shared with a future DPI driver after all.
See wiki[2] for script to make command firmware files.
Noralf.
