Add sound node and dsp-related pieces to enable HDMI+I2S audio playback support on Qualcomm QR2210 RB1 board. That is the only sound output supported for now. The audio playback is verified using the following commands: amixer -c0 cset iface=MIXER,name='SEC_MI2S_RX Audio Mixer MultiMedia1' 1 aplay -D hw:0,0 /usr/share/sounds/alsa/Front_Center.wav Cc: Srinivas Kandagatla <srinivas.kandagatla@linaro.org> Signed-off-by: Alexey Klimov <alexey.klimov@linaro.org> --- arch/arm64/boot/dts/qcom/qrb2210-rb1.dts | 49 ++++++++++++++++++++++++++++++++ 1 file changed, 49 insertions(+)
