The Indiedroid Nova is an SBC from a sub-brand of Ameridroid that
includes the following hardware:

 - A 40-pin GPIO header
 - 2 USB-A 3.0 ports
 - 2 USB-A 2.0 ports
 - A USB-C 2.0 OTG port (used for USB power delivery)
 - A USB-C 3.0 port that can do display port output.
 - A Micro HDMI 2.1 port.
 - A 1GB ethernet port.
 - An RT8821CS based WiFi/Bluetooth module.
 - A user replaceable eMMC module.
 - An SDMMC card slot.
 - A MIPI DSI connector.
 - A MIPI CSI connector.
 - A 3.5mm TRRS audio jack with microphone input.
 - An 2 pin socket for an RTC battery.
 - A 4 pin socket for a debug port.
 - A power button (connected to PMIC), a reset button (connected to SoC
   reset), a boot button, and a recovery button (both connected to the
   ADC).
 - 4GB, 8GB, or 16GB of system RAM.

This initial devicetree includes support for the WiFi, bluetooth,
analog audio out/in, SDMMC, eMMC, RTC, UART debugging, and has
the regulator values from the schematics. ADC, graphics output, GPU,
USB, and wired ethernet are still pending additional upstream changes.
