-* Synopsys DesignWare Cores Mobile Storage Host Controller
-
-Required properties:
-- compatible: should be one of the following:
-    "snps,dwcmshc-sdhci"
-- reg: offset and length of the register set for the device.
-- interrupts: a single interrupt specifier.
-- clocks: Array of clocks required for SDHCI; requires at least one for
-    core clock.
-- clock-names: Array of names corresponding to clocks property; shall be
-    "core" for core clock and "bus" for optional bus clock.
-
-Example:
-	sdhci2: sdhci@aa0000 {
-		compatible = "snps,dwcmshc-sdhci";
-		reg = <0xaa0000 0x1000>;
-		interrupts = <GIC_SPI 21 IRQ_TYPE_LEVEL_HIGH>;
-		clocks = <&emmcclk>;
-		bus-width = <8>;
