* Hisilicon Hi3798CV200 specific extensions to the Synopsys Designware Mobile
|
|
Storage Host Controller
|
|
|
|
Read synopsys-dw-mshc.txt for more details
|
|
|
|
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 Hisilicon Hi3798CV200
|
|
specific extensions to the Synopsys Designware Mobile Storage Host Controller.
|
|
|
|
Required Properties:
|
|
- compatible: Should contain "hisilicon,hi3798cv200-dw-mshc".
|
|
- clocks: A list of phandle + clock-specifier pairs for the clocks listed
|
|
in clock-names.
|
|
- clock-names: Should contain the following:
|
|
"ciu" - The ciu clock described in synopsys-dw-mshc.txt.
|
|
"biu" - The biu clock described in synopsys-dw-mshc.txt.
|
|
"ciu-sample" - Hi3798CV200 extended phase clock for ciu sampling.
|
|
"ciu-drive" - Hi3798CV200 extended phase clock for ciu driving.
|
|
|
|
Example:
|
|
|
|
emmc: mmc@9830000 {
|
|
compatible = "hisilicon,hi3798cv200-dw-mshc";
|
|
reg = <0x9830000 0x10000>;
|
|
interrupts = <GIC_SPI 35 IRQ_TYPE_LEVEL_HIGH>;
|
|
clocks = <&crg HISTB_MMC_CIU_CLK>,
|
|
<&crg HISTB_MMC_BIU_CLK>,
|
|
<&crg HISTB_MMC_SAMPLE_CLK>,
|
|
<&crg HISTB_MMC_DRV_CLK>;
|
|
clock-names = "ciu", "biu", "ciu-sample", "ciu-drive";
