[v1,0/4] arm64: dts: freescale: Add Variscite i.MX8MP DART8MCustomBoard v2

Hello,

This patch series adds support for the Variscite DART8MCustomBoard v2
carrier board with a DART-MX8M-PLUS module.

The device tree code originates from Variscite's BSP, and has been
heavily refactored to adapt to mainline DT bindings. Some features have
been left out:

- Camera: cameras should be enabled through overlays as they're not part
  of the carrier board itself. I have successfully tested both camera
  ports with modules that currently require out-of-tree drivers, so I
  haven't included them in this series.

- HDMI: I have successfully tested this with DT bindings and drivers
  that have been posted to mailing lists but not merged yet. I will
  submit a patch to enable HDMI once the dependencies will be available
  upstream.

- USB OTG: the carrier board has a PTN5150 but doesn't route its
  interrupt pin to the SoC. It should be possible to work around that in
  the driver by implementing polling, but that requires more work that I
  can perform at the moment.

- WiFi, Bluetooth and audio support: those are part of the DART SoM
  itself, for which schematics isn't available, so I can't easily
  troubleshoot them.

- PCIe: I lack test hardware for this.

The LVDS display panel is integrated in the carrier board device tree in
the BSP, I have split it out to an overlay in this series as it is
shipped with the development kit but isn't an integral part of the
carrier board.

May I tempt someone from Variscite to submit patches to enable at least
WiFi, Bluetooth, audio and PCIe ? :-)
