Too bad, I noticed this comment only just now. I'll consider this and
will try again and see how simple-card could be used. There is also the
samsung-i2s-sec secondary 'overlay' CPU DAI that would need to be handled,
and we have it now internally specified in the machine driver through
cpu_dai_name, rather than cpu_of_node.
There might be some more work in the driver needed to support the
secondary I2S interface generically with DT.
