I do appreciate the assistance. In most of this I'm already in water
above my head for the most part, but I'm making progress. Currently have
a booting kernel (4.8-rc4) and usb support, taking a go at the gmac/phy
driver atm. Its mostly similar to an existing driver, but I'd like to
get it up and running since the primary use of this device is over the
network, so even if we did have proper v4l2 devices it would not be
available over the network. One other thing I'm slightly worried about
is the sii/sil9034 hdmi chip included. Apparently its rather tricky to
get a datasheet for this without a NDA due to the drm stuff built in.
