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 ? :-)
