Series sunxi: Introduce H616 support | expand

Commit Message

Jernej Škrabec Jan. 3, 2021, 9:26 a.m. UTC 
OrangePi Zero2 is SBC based on Allwinner H616 with 1 GiB of RAM, SD card
support, gigabit ethernet, micro HDMI, WIFI, Bluetooth and 1 USB 2.0
port. It also has two GPIO headers which allows further peripherals to
be used.

Device Tree file is taken from initial OrangePi Zero2 Linux submission
and it's not yet merged.
