-* 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: should be one of the following
-  - "brcm,bcm7425-sdhci"
-  - "brcm,bcm7445-sdhci"
-  - "brcm,bcm7216-sdhci"
-
-Refer to clocks/clock-bindings.txt for generic clock consumer properties.
-
-Example:
-
-	sdhci@84b0000 {
-		sd-uhs-sdr50;
-		sd-uhs-ddr50;
-		sd-uhs-sdr104;
-		sdhci,auto-cmd12;
-		compatible = "brcm,bcm7216-sdhci",
-			   "brcm,bcm7445-sdhci",
-			   "brcm,sdhci-brcmstb";
-		reg = <0x84b0000 0x260 0x84b0300 0x200>;
-		reg-names = "host", "cfg";
-		interrupts = <0x0 0x26 0x4>;
-		interrupt-names = "sdio0_0";
-		clocks = <&scmi_clk 245>;
-		clock-names = "sw_sdio";
-	};
-
-	sdhci@84b1000 {
-		mmc-ddr-1_8v;
-		mmc-hs200-1_8v;
-		mmc-hs400-1_8v;
-		mmc-hs400-enhanced-strobe;
-		supports-cqe;
-		non-removable;
-		bus-width = <0x8>;
-		compatible = "brcm,bcm7216-sdhci",
-			   "brcm,bcm7445-sdhci",
-			   "brcm,sdhci-brcmstb";
-		reg = <0x84b1000 0x260 0x84b1300 0x200>;
-		reg-names = "host", "cfg";
-		interrupts = <0x0 0x27 0x4>;
-		interrupt-names = "sdio1_0";
-		clocks = <&scmi_clk 245>;
-		clock-names = "sw_sdio";
-	};
