Subject: [PATCH v3 0/5] drm/tiny: panel-mipi-dbi: Support 18 bits per color
 RGB666

Hi,

The binding and driver patches have been reviewed and I appreciate if
someone can take a look at the drm_mipi_dbi patches. The first patch
removes some erroneous big endian code and the 2 other makes it possible
to configure bits per word for the SPI pixel transfer. It's currently
hardcoded for RGB565.

See version 1 of the patchset for the full cover letter.
