+* Marvell sdhci-pxa v2/v3 controller
+
+This file documents differences between the core properties in mmc.txt
+and the properties used by the sdhci-pxav2 and sdhci-pxav3 drivers.
+
+Required properties:
+- compatible: Should be "mrvl,pxav2-mmc", "mrvl,pxav3-mmc" or
+  "marvell,armada-380-sdhci".
+- reg:
+  * for "mrvl,pxav2-mmc" and "mrvl,pxav3-mmc", one register area for
+    the SDHCI registers.
+  * for "marvell,armada-380-sdhci", two register areas. The first one
+    for the SDHCI registers themselves, and the second one for the
+    AXI/Mbus bridge registers of the SDHCI unit.
+
+Optional properties:
+- mrvl,clk-delay-cycles: Specify a number of cycles to delay for tuning.
+
+Example:
+
+sdhci@d4280800 {
+	compatible = "mrvl,pxav3-mmc";
+	reg = <0xd4280800 0x800>;
+	bus-width = <8>;
+	interrupts = <27>;
+	non-removable;
+	mrvl,clk-delay-cycles = <31>;
+};
+
+sdhci@d8000 {
+	compatible = "marvell,armada-380-sdhci";
+	reg = <0xd8000 0x1000>, <0xdc000 0x100>;
+	interrupts = <0 25 0x4>;
+	clocks = <&gateclk 17>;
+	mrvl,clk-delay-cycles = <0x1F>;
+};
