            codec node, as described in ../mfd/arizona.txt;
            the second entry should be phandle of the HDMI
            transmitter node
    
  • i2s-controller : the list of phandle and argument tuples pointing to
            I2S controllers, the first entry should be I2S0 and
            the second one I2S1
    
  • audio-amplifier : the phandle of the MAX98504 amplifier
