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;
|
};
