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.
Looks alright, the same story here with the DT. I updated to v3, with
the prospect of updating this later in the cycle when needed.
I dropped the Ethernet support from the defconfig for now, as I moved
the EMAC driver fixes out of this initial series. Ideally we can still
get them merged next week.
