Add support for the Bananapi R2 (BPI-R2) development board from
BIPAI KEJI. Detailed hardware information for BPI-R2 which could be
found on http://www.banana-pi.org/r2.html
The patch currently only adds Mediatek GMAC, MT7530 Switch, the crypto
engine, USB, IR, I2S, I2C, UART, SPI, PWM, GPIO keys, GPIO LEDs and
PMIC LEDs. As to the other missing hardware and peripherals, they would
be added and integrated continuously.

What is this reg needed for? I can't find it neither in the code nor in the
bindings (mt7530 and general dsa bindings). Actually it throws a warning when
compiling:
arch/arm/boot/dts/mt7623n-bananapi-bpi-r2.dtb: Warning (reg_format): "reg"
property in /ethernet@1b100000/mdio-bus/switch@0 has invalid length (4 bytes)
