* 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;

	};
