| |
This patch enables a PiFi DAC+ V2.0, which is a PCM5122-based audio output DAC add-on board for the Raspberry Pi B+ and later, connected to the GPIO header of the Bananapi M3 via jumper cables. The power, ground, and I2C pins are in the same position, but the I2S ones are not.
The I2C controller used is I2C2, while the I2S controller is I2S1.
