Subject: [PATCH v1 15/19] arm: dts: mt7623: add SPI[1,2], I2C2 and sound related nodes to reference board

From: Sean Wang <sean.wang@...iatek.com>

There are SPI[1,2] and I2C2 and sound device with WM8960 codec which
MT7623 reference board is equipped with.

However, some of those devices cannot be found on bananapi-r2, they should
be disabled properly for that.
