"D1 Nezha" is Allwinner's first-party development board for the D1 SoC.
It was shipped with 512M, 1G, or 2G of DDR3. It supports onboard audio,
HDMI, gigabit Ethernet, WiFi and Bluetooth, USB 2.0 host and OTG ports,
plus low-speed I/O from the SoC and a GPIO expander chip.

Changes in v2:
 - Common regulators moved to MangoPi MQ patch, removed analog LDOs
 - Removed LRADC (depends on analog LDOs)
 - Added XR829 host-wake interrupt
