Merge tag 'sunxi-drm-for-4.10' of https://git.kernel.org/pub/scm/linux/kernel/git/mripard/linux into drm-next
sun4i-drm changes for 4.10
Support for the Allwinner A31 SoC display engine using the sun4i-drm
driver.
* tag 'sunxi-drm-for-4.10' of https://git.kernel.org/pub/scm/linux/kernel/git/mripard/linux:
drm/sun4i: Add a few formats
drm/sun4i: Add compatible strings for A31/A31s display pipelines
drm/sun4i: Add compatible string for A31/A31s TCON (timing controller)
drm/sun4i: tcon: Move SoC specific quirks to a DT matched data structure
drm/sun4i: sun6i-drc: Support DRC on A31 and A31s
