The ROCK64 is a credit card size 4K60P HDR Media Board Computer using the
Rockchip RK3328 Quad-Core ARM Cortex A53 64-Bit Processor and supporting
up to 4GB 1600MHz LPDDR3 memory. It provides eMMC module socket, MicroSD
Card slot, Pi-2 Bus, Pi-P5+ Bus, USB 3.0 and many others peripheral
devices interface for makers to integrate with sensors and devices.
The devicetree currently supports basic peripherals, with more to be
added later on.

Depends on rk805 pmic support landing, which hopefully will happen
in the next days.
