Subject: [PATCH v8 0/3] Add support rockchip RGB output interface

This patches add support rockchip RGB output, Some Rockchip CRTCs, like
rv1108 and px30 can directly output parallel and serial RGB data to panel
or to conversion chip.
So add a feature-bit for vops to mark the ability for these direct outputs
and add an internal encoder in that case, that can attach to bridge chips
or panels.

Hi Sandy,

while reviewing my own code in patch1, I found that it was missing
correct put calls for node and pdev and also made it behave better
if no device is present.

While we don't need that right now, it makes it possible to
distinguish between subdriver, external bridge or no device later
on if needed.

I've also updated the documentation of the function a bit, so that
people looking at it can grasp it hopefully easier :-)

And finally I've dropped the Review tag from Mark. He isn't at
Rockchip for a while now and the driver did change over time a bit.

So if you have time, please take a final look at it.
