Great - I fully agree that this needs to be renamed as it is a Designware

Should it be moved into bridge/ ?  It isn't implemented as a DRM bridge
driver at present, so this seems illogical.  Is the longer term plan to
convert it to be a DRM bridge?

Secondly, if you want HDMI audio support, you may find the patches I
maintain for the SolidRun devices useful, which add this as a standard
ALSA device.  I also have CEC support for it as well.  If you're
interested, I'll email those.

FTTC broadband for 0.8mile line: currently at 9.5Mbps down 400kbps up
according to speedtest.net.
