Add support rockchip RGB output interface

A patchset in state Maintainer-tree for linux-kernel

From: Heiko Stuebner <heiko@...> Date: Thu, 30 Aug 2018 23:05:46 +0200

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.
