+Broadcom BCM2835 SDHCI controller
+
+This file documents differences between the core properties described
+by mmc.txt and the properties that represent the BCM2835 controller.
+
+Required properties:
+- compatible : Should be "brcm,bcm2835-sdhci".
+- clocks : The clock feeding the SDHCI controller.
+
+Example:
+
+sdhci: sdhci {
+ compatible = "brcm,bcm2835-sdhci";
+ reg = <0x7e300000 0x100>;
+ interrupts = <2 30>;
+ clocks = <&clk_mmc>;
+ bus-width = <4>;
+};
