[PATCH] ARM: sun8i: Add Parrot Board DTS

From: Quentin Schulz
Date: Mon Jun 13 2016 - 06:16:53 EST

The Parrot Board is an evaluation board with an Allwinner R16 (assumed
to be close to an Allwinner A33), 4GB of NAND, 512MB of RAM, USB host
and OTG, a WiFi/Bluetooth combo chip, a micro SD Card reader, 2
controllable buttons, an LVDS port with separated backlight and
capacitive touch panel ports, an audio/microphone jack, a camera CSI
port, 2 sets of 22 GPIOs and an accelerometer.
