I was reminded of this since it would have made it easy to turn off the panel and see if it turned white. Adding this makes it possible to send commands from userspace for testing:
.debugfs_init = mipi_dbi_debugfs_init,
If you do that you have to set this to NULL since it's not possible to read from the controller in this panel:
mipi->read_commands = NULL;
Noralf.
