|
|
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>;
|
||
|
|
