* 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";

	};
