- interrupts: Interrupts used by the MMC controller.



Required properties:

- bus-width: Number of data lines, can be <1>, <4>, or <8>



Optional properties:

- cd-gpios: Specify GPIOs for card detection, see gpio binding

- wp-gpios: Specify GPIOs for write protection, see gpio binding

- cd-inverted: when present, polarity on the wp gpio line is inverted

- cd-inverted: when present, polarity on the cd gpio line is inverted

- wp-inverted: when present, polarity on the wp gpio line is inverted

- non-removable: non-removable slot (like eMMC)

- max-frequency: maximum operating clock frequency
