BQ the company is no more. So I have no issue with me being in there,
afterall I did that driver back then, but I guess my main and permanent
address of heiko@sntech.de might be more appropriate :-)

well, apparently my get_maintainer.pl | confirm_and_add_addresses | git send-email
script did not run in the kernel checkout I applied the patch to, so it did
not catch that address. Sorry. BTW: What is common practice for the maintainer address
in the binding in conversions? Here I looked at the commits of the plaintext binding.

The display is in landscape orientation, but the touchscreen is in portrait
orientation. Specify that properly in the devicetree.
