+* STMicroelectronics sdhci-st MMC/SD controller
+
+This file documents differences between the core properties in mmc.txt
+and the properties used by the sdhci-st driver
+
+Required properties:
+- compatible: "st,sdhci"
+- clocks: card clock, must be "mmc".
+
+Optional properties:
+- reset: to provide a reset to the HC.
+- non-removable: non-removable slot (bindings/mmc/mmc.txt).
+
+Example:
+
+mmc0: sdhci at fe81e000 {
+	compatible	= "st,sdhci";
+	status		= "disabled";
+	reg		= <0xfe81e000 0x1000>;
+	interrupts	= <GIC_SPI 127 IRQ_TYPE_NONE>;
+	interrupt-names	= "mmcirq";
+	pinctrl-names	= "default";
+	pinctrl-0	= <&pinctrl_mmc0>;
+	clock-names	= "mmc";
+	clocks		= <&clk_s_a1_ls 1>;
+};
