[PATCH 00/21] drm: mxsfb: Add i.MX7 support

Hello,

This patch series adds i.MX7 support to the mxsfb driver. The eLCDIF
instance found in the i.MX7 is backward-compatible with the already
supported LCDC v4, but has extended features amongst which the most
notable one is a second plane.

The first 9 patches (01/21 to 09/21) contain miscellaneous cleanups and
refactoring to prepare for what is to come. Patch 10/21 starts the real
work with removal of the DRM simple display pipeline helper, as it
doesn't support multiple planes. The next patch (11/21) is an additional
cleanup.

Patches 12/21 to 14/21 fix vblank handling that I found to be broken
when testing on my device. Patch 15/21 then performs an additional small
cleanup, and patch 16/21 starts official support for i.MX7 by mentioning
it in Kconfig.

Patch 17/21 adds a new device model for the i.MX6SX and i.MX7 eLCDIF.
After three additional cleanups in patches 18/21 to 20/21, patch 21/21
finally adds support for the second plane.

The code is based on drm-misc-next and has been tested on an i.MX7D
platform with a DPI panel.
