[RFC PATCH v1 0/4] Add Rockchip RGA support

[ykk@rock-chips.com (Yakir Yang)]

Hi, Mark and all.

This patch set would add the RGA direct rendering based 2d graphics
acceleration module.

This patch set is based on git repository below:
git://people.freedesktop.org/~airlied/linux drm-next
commit id: 568d7c764ae01f3706085ac8f0d8a8ac7e826bd7

And the RGA driver is based on Exynos G2D driver, it only manages the
command lists received from user, so user should make the command list
to data and registers needed by operation to use.

I have prepared an userspace demo application for testing:
	https://github.com/yakir-Yang/libdrm-rockchip
That is a rockchip libdrm library, and I have write a simple test case
"rockchip_rga_test" that would test the below RGA features:
- solid
- copy
- rotation
- flip
- window clip
- dithering

Thanks,
- Yakir
