  77 Notes:
  78 * group "mpp_audio1" allows the following functions and gpio pins:
  79   - gpio          : gpio on pins 52-57
  80   - i2s1/spdifo   : audio1 i2s on pins 52-55 and spdifo on 57, no gpios
  81   - i2s1          : audio1 i2s on pins 52-55, gpio on pins 56,57
  82   - spdifo        : spdifo on pin 57, gpio on pins 52-55
  83   - twsi          : twsi on pins 56,57, gpio on pins 52-55
  84   - ssp/spdifo    : ssp on pins 52-55, spdifo on pin 57, no gpios
  85   - ssp           : ssp on pins 52-55, gpio on pins 56,57
  86   - ssp/twsi      : ssp on pins 52-55, twsi on pins 56,57, no gpios
  87 * group "audio0" internally muxes i2s0 or ac97 controller to the dedicated
  88   audio0 pins.
  89 * group "twsi" internally muxes twsi controller to the dedicated or option pins.
