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 added nodes into the SoC-level file mt7623.dtsi such as CPU OPP table and thermal zone treating CPU as one of cooling devices and also added nodes into board-level file mt7623n-bananapi-bpi-r2.dts such as 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.
