So far, from my side, now most of changes have been submitted /
merged.  But I still have some unclear things in the code.

- The PCM format: the code contains the handling of S16_LE, but it
  doesn't seem work when I enabled the info bit.  What's missing?
  Also U24_LE format is ever supported...?  How?

- The behavior in had_process_buffer_underrun() isn't clear enough.
  Or, more exactly, the behavior of AUD_HDMI_STATUS reg and AUD_CONFIG
  reg look complex, and need a bit more description for readers
  (including me).

Can you guys enlighten a bit?


thanks,

Takashi
