Notes:
- group “mpp_audio1” allows the following functions and gpio pins:
- gpio : gpio on pins 52-57
- i2s1/spdifo : audio1 i2s on pins 52-55 and spdifo on 57, no gpios
- i2s1 : audio1 i2s on pins 52-55, gpio on pins 56,57
- spdifo : spdifo on pin 57, gpio on pins 52-55
- twsi : twsi on pins 56,57, gpio on pins 52-55
- ssp/spdifo : ssp on pins 52-55, spdifo on pin 57, no gpios
- ssp : ssp on pins 52-55, gpio on pins 56,57
- ssp/twsi : ssp on pins 52-55, twsi on pins 56,57, no gpios
- group “audio0” internally muxes i2s0 or ac97 controller to the dedicated
audio0 pins. - group “twsi” internally muxes twsi controller to the dedicated or option pins.
