+* PXA MMC drivers
+
+Driver bindings for the PXA MCI (MMC/SDIO) interfaces
+
+Required properties:
+- compatible: Should be "marvell,pxa-mmc".
+- vmmc-supply: A regulator for VMMC
+
+Optional properties:
+- marvell,detect-delay-ms: sets the detection delay timeout in ms.
+- marvell,gpio-power: GPIO spec for the card power enable pin
+
+This file documents differences between the core properties in mmc.txt
+and the properties used by the pxa-mmc driver.
+
+Examples:
+
+mmc0: mmc@41100000 {
+       compatible = "marvell,pxa-mmc";
+       reg = <0x41100000 0x1000>;
+       interrupts = <23>;
+       cd-gpios = <&gpio 23 0>;
+       wp-gpios = <&gpio 24 0>;
+};
