-These properties are common to multiple MMC host controllers. Any host
-that requires the respective functionality should implement them using
-these definitions.
-
-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
-- 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
-
-Example:
-
-sdhci@ab000000 {
- compatible = "sdhci";
- reg = <0xab000000 0x200>;
- interrupts = <23>;
- bus-width = <4>;
- cd-gpios = <&gpio 69 0>;
- cd-inverted;
- wp-gpios = <&gpio 70 0>;
- max-frequency = <50000000>;
