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