mediatek: bananapi-r3: add overlay for ReSpeaker 2-mic hat
Add DT overlay to allow using the ReSpeaker 2-mic hat connected to
the 26-pin header of the BananaPi BPi-R3.
Supported sample formats: S16_LE, S24_LE, S32_LE
Supported sample rates: 8/12/16/24/32/48/96/192 kHz
| BPi-R3 | ReSpeaker 2-mic
Signal | 26-pin | 40-pin
----------+----------+-------------------
VCC 5V | 2 | 2
I2C SDA | 3 | 3
I2C SCL | 5 | 5
GND | 6 | 6
PCM CLK | 12 | 12
PCM FS | 15 | 35
PCM DIN | 26 | 38
GND | 25 | 39
PCM DOUT | 22 | 40
Once connected, install the driver and tell U-Boot to apply the DT
overlay:
opkg kmod-sound-soc-mt7986-wm8960
fw_setenv bootconf_base "config-mt7986a-bananapi-bpi-r3#mt7986a-bananapi-bpi-r3-respeaker-2mics"
reboot
To setup the ReSpeaker for Stereo out on the Headphone plug:
amixer sset 'Right Output Mixer PCM' on
amixer sset 'Left Output Mixer PCM' on
amixer sset 'PCM Playback -6dB' off
amixer sset 'O018 I150_Switch' on
amixer sset 'O019 I151_Switch' on
amixer sset 'O124 I032_Switch' on
amixer sset 'O125 I033_Switch' on
amixer sset 'Headphone' 121
amixer sset 'Playback' 255
