+- 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>;
