Shawn Guo	9e42b263e8	drm: zte: move CSC register definitions into a common header ... The CSC (Color Space Conversion) block in VOU is used by not only Graphic Layer (plane) but also channel (CRTC) module. Let's move its register definitions into a common header, so that CRTC driver can include it when needed.

Shawn Guo	4e986d3705	drm: zte: add overlay plane support ... It enables VOU VL (Video Layer) to support overlay plane with scaling function. VL0 has some quirks on scaling support. We choose to skip it and only adds VL1 and VL2 into DRM core for now. Function zx_plane_atomic_disable() gets moved around with no changes to save a forward declaration.

Shawn Guo	0a886f5952	drm: zte: add initial vou drm driver ... It adds the initial ZTE VOU display controller DRM driver. There are still some features to be added, like overlay plane, scaling, and more output devices support. But it's already useful with dual CRTCs and HDMI monitor working.
