In fact, there should be no audio card driver as proposed here:
with such a simple layout
CPU DAI (sun4i-a10-i2s) -> CODEC DAI (sun8i-a33-codec)
the 'simple-card' does the job.
BTW, I have a I2S/PCM/TDM driver for the H3 and A83T.
But, as it works with HDMI and contains echanges with the DRM driver,
it cannot go yet to the mainline...
