2019-07-20drm/sun4i: sun8i-csc: Add support for color encoding and rangeJernej Skrabec
Conversion from YUV to RGB depends on range (limited or full) and encoding (BT.601 or BT.709). Current code doesn't consider this and always uses BT.601 encoding and limited range. Fix this by introducing new CSC matrices, which are selected based on range and encoding parameters.

2019-07-20drm/sun4i: sun8i_csc: Simplify register writesJernej Skrabec
It turns out addition of 0x200 to constant parts (+0.5) is not really necessary. Besides, we can consider that before and fix value in CSC matrix. This simplifies register writes quiet a bit.

2019-07-17drm/sun4i: drop use of drmP.hSam Ravnborg
Drop use of the deprecated drmP.h header file. While touching the list of include file, use the typical order of the blocks: \#include <linux/*> \#include <video/*> \#include <drm/*> \#include "" Within each block, sort the files. Include necessary files to fix build after the drmP.h removal.

2018-11-05drm/sun4i: Add basic support for DE3Jernej Skrabec
Display Engine 3 is an upgrade of DE2 with new features like support for 10 bit color formats and support for AFBC. Most of DE2 code works with DE3, except some small details. Implement basic support for DE3. Support for 10 bit colort formats and AFBC, among others missing features, will be added later.

2017-12-05drm/sun4i: Add DE2 CSC libraryJernej Skrabec
DE2 have many CSC units - channel input CSC, channel output CSC and mixer output CSC and maybe more. Fortunately, they have all same register layout, only base offsets differs. Add support only for channel output CSC for now.
