+Qualcomm Snapdragon SDHCI controller
+
+Required properties:
+- compatible : "qcom,sdhci-msm-v4"
+- reg: Base address and length of registers:
+	- Host controller registers (SDHCI)
+	- SD Core registers
+- clock: interface clock (must accept SD bus clock as a frequency)
+
+Optional properties:
+- index: If there is more than one controller - controller index (required
+	by generic SDHCI code).
+- bus_width: Width of SD/eMMC bus (default 4)
+- clock-frequency: Frequency of SD/eMMC bus (default 400 kHz)
+
+Example:
+
+sdhci@07864000 {
+	compatible = "qcom,sdhci-msm-v4";
+	reg = <0x7864900 0x11c 0x7864000 0x800>;
+	index = <0x1>;
+	bus-width = <0x4>;
+	clock = <&clkc 1>;
+	clock-frequency = <200000000>;
+};

+Synopsys Designware Mobile Storage Host Controller extensions
+used in Synopsys ARC devboards
+
+Required Properties:
+
+* compatible: should be - "snps,dw-mshc".
+* bus-width: number of data lines connected to the controller.
+* clocks: from common clock binding: handle to biu and ciu clocks for the
+  bus interface unit clock and the card interface unit clock.
+* clock-names: from common clock binding: Shall be "biu" and "ciu".
+
+Optional properties:
+
+* fifo-depth: The maximum size of the tx/rx fifo's. If this property is not
+  specified, the default value of the fifo size is determined from the
+  controller registers.
+* fifo-mode: Don't use DMA.
+* max-frequency: Maximum operating clock frequency, driver uses 'ciu' clock
+  frequency if it is not set.
+
+Example:
+
+mmc0@f000a000 {
+	compatible = "snps,dw-mshc";
+	reg = <0xf000a000 0x400>;
+
+	bus-width = <4>;
