You should put changelog here when you send new version of the patch.

Drop everything related to hdmi audio. There was quite a few e-mails regarding 
how to best approach hdmi audio implementation on A64 and other SoCs with DW 
HDMI core. Agreement is that we should introduce HDMI audio card driver 
instead of simple audio card. I have this almost implemented, but I didn't find 
time to polish it. Another thing is that there is nothing board specific about 
HDMI audio, so nodes should reside in SoC DTSI file anyway.

Best regards,
Jernej
