The Chameleon board is an OpenHardware devboard made by YuzukiTsuru.
The form factor resembles the Raspberry Pi Model A boards, though it
differs significantly in its features:

  - Allwinner H618 SoC (4 * Arm Cortex-A53 cores, 1MB L2 cache, 1.4 GHz)
  - between 512MiB and 2GiB DDR3 DRAM
  - up to 128 GiB eMMC flash
  - AXP313a PMIC
  - 100 Mbit/s Ethernet pins on a header
  - XR829 WIFI+Bluetooth chip
  - 4 * USB 2.0 USB-C ports
  - microSD card slot
  - 3.5mm A/V port

Add the devicetree describing the board's peripherals and their
connections.

OTG role contradicts text above.

The rest looks good.
