[PATCH v4 0/2] arm64: dts: imx8mq: Add NWL DSI host controller to Librem 5 Devkit

[PATCH v4 0/2] arm64: dts: imx8mq: Add NWL DSI host controller to Librem 5 Devkit

[Guido Günther]

These patches add the NWL host controller to the imx8mq and make use of it on
the Librem 5 Devkit enabling the built in MIPI DSI LCD panel.

I opted to add imx8mq internal ports and endpoints between nwl and lcdif to the
generic dtsi since those are SOC rather than board specific properties.

Changes from v3
- Rebase patch 3 and 4 against Shawn's imx/defconfig
  Patches 1 an 2 got already applies, thanks!

Changes from v2
- Add Tested-by from Martin Kepplinger, thanks!

- As per review comment by Fabio Estevam
  Re-sync DRM related defconfig bits. I didn't resyc the whole defconfig since
  this is pretty much kernel version dependent.

Enable the panel, NWL DSI host controller and dphy. This
also needs the reset controller.
