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.
