From: Sean Wang <sean.wang@xxxxxxxxxxxx> 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.
