+* BROADCOM BRCMSTB/BMIPS SDHCI Controller
+
+This file documents differences between the core properties in mmc.txt
+and the properties used by the sdhci-brcmstb driver.
+
+NOTE: The driver disables all UHS speed modes by default and depends
+on Device Tree properties to enable them for SoC/Board combinations
+that support them.
+
+Required properties:
+- compatible: "brcm,bcm7425-sdhci"
+
+Refer to clocks/clock-bindings.txt for generic clock consumer properties.
+
+Example:
+
+ sdhci@f03e0100 {
+ compatible = "brcm,bcm7425-sdhci";
+ reg = <0xf03e0000 0x100>;
+ interrupts = <0x0 0x26 0x0>;
+ sdhci,auto-cmd12;
+ clocks = <&sw_sdio>;
+ sd-uhs-sdr50;
+ sd-uhs-ddr50;
+ };
+
+ sdhci@f03e0300 {
+ non-removable;
+ bus-width = <0x8>;
+ compatible = "brcm,bcm7425-sdhci";
+ reg = <0xf03e0200 0x100>;
+ interrupts = <0x0 0x27 0x0>;
+ sdhci,auto-cmd12;
+ clocks = <sw_sdio>;
+ mmc-hs200-1_8v;
