2*4882a593Smuzhiyun
3*4882a593SmuzhiyunRequired properties:
4*4882a593Smuzhiyun- compatible: should be one of the following:
5*4882a593Smuzhiyun    "snps,dwcmshc-sdhci"
6*4882a593Smuzhiyun- reg: offset and length of the register set for the device.
7*4882a593Smuzhiyun- interrupts: a single interrupt specifier.
8*4882a593Smuzhiyun- clocks: Array of clocks required for SDHCI; requires at least one for
9*4882a593Smuzhiyun    core clock.
10*4882a593Smuzhiyun- clock-names: Array of names corresponding to clocks property; shall be
11*4882a593Smuzhiyun    "core" for core clock and "bus" for optional bus clock.
