Pull drm updates from Davbe Airlie:
 "This is the main pull request for graphics for 5.6. Usual selection of
  changes all over.

  I've got one outstanding vmwgfx pull that touches mm so kept it
  separate until after all of this lands. I'll try and get it to you

+ * DOC: Driver for the ARM FrameBuffer Compression Decoders
+ *
+ * The Amlogic GXM and G12A SoC families embeds an AFBC Decoder,
+ * to decode compressed buffers generated by the ARM Mali GPU.
+ *
+ * For the GXM Family, Amlogic designed their own Decoder, named in
+ * the vendor source as "MESON_AFBC", and a single decoder is available
+ * for the 2 OSD planes.
+ * This decoder is compatible with the AFBC 1.0 specifications and the
+ * Mali T820 GPU capabilities.
+ * It supports :
+ * - basic AFBC buffer for RGB32 only, thus YTR feature is mandatory
+ * - SPARSE layout and SPLIT layout
+ * - only 16x16 superblock
+ *
+ * The decoder reads the data from the SDRAM, decodes and sends the
+ * decoded pixel stream to the OSD1 Plane pixel composer.
+ *
+ * For the G12A Family, Amlogic integrated an ARM AFBC Decoder, named
+ * in the vendor source as "MALI_AFBC", and the decoder can decode up
+ * to 4 surfaces, one for each of the 4 available OSDs.
+ * This decoder is compatible with the AFBC 1.2 specifications for the
+ * Mali G31 and G52 GPUs.
+ * Is supports :
+ * - basic AFBC buffer for multiple RGB and YUV pixel formats
+ * - SPARSE layout and SPLIT layout
+ * - 16x16 and 32x8 "wideblk" superblocks
+ * - Tiled header
+ *
+ * The ARM AFBC Decoder independent from the VPU Pixel Pipeline, so
+ * the ARM AFBC Decoder reads the data from the SDRAM then decodes
+ * into a private internal physical address where the OSD1 Plane pixel
+ * composer unpacks the decoded data.
