[U-Boot] [PATCH] sunxi: Add defconfig and DTS file for Allwinner R16 EVB (Parrot)

Quentin Schulz quentin.schulz at free-electrons.com
Fri Jun 24 14:33:35 CEST 2016 

The Parrot Board is an evaluation board with an Allwinner R16 (assumed
to be close to an Allwinner A33), 4GB of eMMC, 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.

The DTS file is identical to the one submitted to the upstream kernel.
