- part and usage.
- Required properties:
- - compatible: "marvell,dove-pinctrl"
- - clocks: (optional) phandle of pdma clock
- Available mpp pins/groups and functions:
- Note: brackets (x) are not part of the mpp name for marvell,function and given
- only for more detailed description in this document.

- 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.
