+* Atmel SDHCI controller
+
+This file documents the differences between the core properties in
+Documentation/devicetree/bindings/mmc/mmc.txt and the properties used by the
+sdhci-of-at91 driver.
+
+Required properties:
+- compatible:           Must be "atmel,sama5d2-sdhci".
+- clocks:               Phandlers to the clocks.
+- clock-names:          Must be "hclock", "multclk", "baseclk";
+
+
+Example:
+
+sdmmc0: sdio-host@a0000000 {
+        compatible = "atmel,sama5d2-sdhci";
+        reg = <0xa0000000 0x300>;
+        interrupts = <31 IRQ_TYPE_LEVEL_HIGH 0>;
+        clocks = <&sdmmc0_hclk>, <&sdmmc0_gclk>, <&main>;
+        clock-names = "hclock", "multclk", "baseclk";
+};
