2017-12-05drm/sun4i: Reorganize UI layer code in DE2Jernej Skrabec
Till now, DE2 driver supported only UI planes. Before we add support for VI planes, lets split out UI layer specific code from common parts. This commit does the following: - renames sun8i_layer.c to sun8i_ui_layer.c - moves UI channel specific code to sun8i_ui_layer.c - moves common code from sun8i_layer.c to sun8i_mixer.c - renames function and structure names so it is apparent where they belong to No functional change is made.

2017-12-05drm/sun4i: Start using layer id in DE2 driverJernej Skrabec
Till now, plane selection was hardcoded to first overlay in first UI channel and layer parameter is unused. Rename and add parameters to layer functions so they would represent HW more accurately and start using then. It turns out that overlays don't fit well in current DRM design, because they can't be blended together or scaled independetly when they are set to same channel. Because of that, always use only first overlay in each channel.

2017-06-01drm/sun4i: add support for Allwinner DE2 mixersIcenowy Zheng
Allwinner have a new "Display Engine 2.0" in their new SoCs, which comes with mixers to do graphic processing and feed data to TCON, like the old backends and frontends. Add support for the mixer on Allwinner V3s SoC; it's the simplest one. Currently a lot of functions are still missing -- more investigations are needed to gain enough information for them.
