From 38be6b838780e8ad0ee80e716752c8843cd87e05 Mon Sep 17 00:00:00 2001 From: Jernej Skrabec Date: Mon, 11 Jan 2021 21:11:53 +0100 Subject: [PATCH] sunxi: Add support for OrangePi Zero2 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. The devicetree file is taken from v3 of the OrangePi Zero2 Linux submission [1], which it's not yet merged.
