  This patch will enable interrupts from AC97C and report about error
  conditions that occurs.

  On channel A both overrun and underrun will be enabled depending if
  playback and/or capture are enabled. On the control channel the overrun
  interrupt is enabled.

• c42eec0f1   ALSA: snd-atmel-ac97c: set correct size for buffer hardware parameter ... Browse Code »

  This patch will set a proper maximum bytes for the buffer, which is:
  channels * bytes per sample * maximum periods * maximum bytes per period.

  It also sets the minimum periods to 6, a value chosen from testing, with
  a minimum of 6 periods the system has good time to fill in new audio
  data without skipping.

  This patch will take care not to overwrite OCA and ICA registers when
  assigning input and output channels. It will also make sure the
  registers are at a known state when enabling a channel and clean up
  properly in case of an error.
