* 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";
	};
