The Compulab SB-UCM-iMX8MPLUS is a carrier board designed as an
evaluation board for the UCM-iMX8M-Plus SoM. It integrates support for
ethernet, USB, display (HDMI, DSI and LVDS), cameras (CSI-2 and GMSL),
audio and various other peripherals. Add a .dts that models the SB-UCM.
Not all peripherals present on the board are enabled yet, due to missing
support in mainline, or just because I couldn't test them all. Missing
features include PCIe, audio, camera, display, SIM and CAN. The I2C, SPI
and other buses routed to extensions connectors have also not been
tested. They can be added to the device tree at a later time.
