* 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>;
}
