[PATCH 5/5] arm64: dts: qcom: qrb2210-rb1: add HDMI/I2S audio playback support
Posted by Alexey Klimov 11 months, 2 weeks ago 
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
