From: Frieder Schrempf <frieder.schrempf at kontron.de>

This patchset contains several improvements and updates for the devicetrees
for the i.MX8MM modules and boards by Kontron Electronics GmbH.

* Misc cleanups and small fixes
* OSM-S i.MX8MM module refactoring and update to latest HW revision

Changes in v4:
* Rebase to Shawn's imx/dt64 branch
* Drop patches 1 and 2 (display support) as there are unresolved DTC warnings
  and I am not sure how to resolve them at the moment.

Changes in v3:
* Address Shawn's review comments for patch 1, 2 and 14 (thanks!)

Changes in v2:
* Rework DSI mux GPIO logic to be compatible with overlay
* Switch from 4 to 2 DSI lanes for LVDS bridge to fix non-working display
