| 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. |
