78Notes:
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.
