Add support for audio capture using onboard DMIC. It is directly connected to vamacro and txmacro without any soundwire interfaces. The capture was verified using the following commands: amixer -c0 cset iface=MIXER,name='MultiMedia3 Mixer VA_CODEC_DMA_TX_0' 1 amixer -c0 cset iface=MIXER,name='VA_AIF1_CAP Mixer DEC0' 1 amixer -c0 cset iface=MIXER,name='VA_DEC0 Volume' 110 amixer -c0 cset iface=MIXER,name='VA DMIC MUX0' 2 arecord -D hw:0,2 -f S16_LE -c 2 -r 48000 -d 5 record.wav Cc: Srinivas Kandagatla <srini@kernel.org> Signed-off-by: Alexey Klimov <alexey.klimov@linaro.org> --- arch/arm64/boot/dts/qcom/qrb4210-rb2.dts | 22 ++++++++++++++++++++++ 1 file changed, 22 insertions(+)
