+* ZTE specific extensions to the Synopsys Designware Mobile Storage
+ Host Controller
+
+The Synopsys designware mobile storage host controller is used to interface
+a SoC with storage medium such as eMMC or SD/MMC cards. This file documents
+differences between the core Synopsys dw mshc controller properties described
+by synopsys-dw-mshc.txt and the properties used by the ZTE specific
+extensions to the Synopsys Designware Mobile Storage Host Controller.
+
+Required Properties:
+
+* compatible: should be
+ - "zte,zx296718-dw-mshc": for ZX SoCs
+
+Example:
+
+ mmc1: mmc@1110000 {
+ compatible = "zte,zx296718-dw-mshc";
+ reg = <0x01110000 0x1000>;
+ interrupts = <GIC_SPI 15 IRQ_TYPE_LEVEL_HIGH>;
