Subject: [PATCH] ARM: dts: sun7i: Add dts file for Sinovoip BPI-M1+
The BPI-M2+ is an A20 development board. It is an improvement over
the original Banana Pi, much like the Raspberry Pi B+ over the RPi B.
The form factor and connectors are similar to the RPi B+. The board
is also similar in design to LeMaker's Banana Pro, but the actual
wiring is different.
It has 1GB DRAM, a micro SD card slot, HDMI output, 2 USB host connector
and 2 USB Micro OTG connector (1 for OTG, 1 only for power), an IR
receiver, gigabit Ethernet with a Realtek RTL8211E PHY, SDIO WiFi based
on Ampak AP6181.
The board also has a 3 pin header for (debug) UART, a 40 pin GPIO header
based on the Raspberry Pi B+, but the peripheral signals are not the
same. There are 2 FPC connectors, 1 for connecting BPI's camera, the
other for BPI's LCD screen.
Standard peripherals on the GPIO header matching the ones found on the
Raspberry Pi B+/2 are enabled by default. This includes i2c2, i2c3,
spi0, uart3.
