+* Marvell orion-sdio controller
+
+This file documents differences between the core properties in mmc.txt
+and the properties used by the orion-sdio driver.
+
+- compatible: Should be "marvell,orion-sdio"
+- clocks: reference to the clock of the SDIO interface
+
+Example:
+
+ mvsdio@d00d4000 {
+ compatible = "marvell,orion-sdio";
+ reg = <0xd00d4000 0x200>;
+ interrupts = <54>;
+ clocks = <&gateclk 17>;
+ };
