[1/9] video: initial support for ADV7180
Commit Message
From: Richard Röjfors <richard.rojfors.ext@mocean-labs.com>
This is an initial driver for Analog Devices ADV7180 Video Decoder.
So far it only supports query standard.

I'm working on drivers for the intel in-vehicle infotainment development
board:
http://edc.intel.com/Applications/In-Vehicle-Infotainment/Low-Power/
> And what is the point of merging such a limited driver?
All of the drivers goes into moblin IVI, and the goal is to commit all
the drivers to the kernel.
I agree, this is an initial limited driver, but functionality can/will
be added incrementally when needed.
There is a video driver, which will be committed later which uses this
subdev.
I will update the driver according to you comments, and post it in a
couple of days,
thanks
