* 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>;
fifo-depth = <32>;
data-addr = <0x200>;
fifo-watermark-aligned;
bus-width = <4>;
clock-frequency = <50000000>;
clocks = <&topcrm SD0_AHB>, <&topcrm SD0_WCLK>;
clock-names = "biu", "ciu";
max-frequency = <50000000>;
cap-sdio-irq;
cap-sd-highspeed;
};
