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.
