I'll be glad to move the driver to their subsystem if you think it's a
the better place. Basically there are two reasons why I send the
driver to the staging directory. The first one is because my test
environment is a bit limited, with my environment I can only test the
HDMI to DisplayPort pass-through mode so the driver builds but it's
partially tested. The second one is that I expect I'll need to
refactor some code, specially in slimport_tx_drv.c file to be
accepted, I decided not change too much this file from the original to
not break the functionality, so I thought that will be better send
first to the staging driver to have first reviews.

ok, I'll add in the next series once received some feedback (or move
to the video subsystem)

Thanks,
