1These properties are common to multiple MMC host controllers. Any host
2that requires the respective functionality should implement them using
3these definitions.

5Required properties:
6- bus-width: Number of data lines, can be <1>, <4>, or <8>
7
8Optional properties:
9- cd-gpios : Specify GPIOs for card detection, see gpio binding
10- wp-gpios : Specify GPIOs for write protection, see gpio binding
11- cd-inverted: when present, polarity on the wp gpio line is inverted
12- wp-inverted: when present, polarity on the wp gpio line is inverted
13- non-removable: non-removable slot (like eMMC)
14- max-frequency: maximum operating clock frequency
