1 | * ZTE specific extensions to the Synopsys Designware Mobile Storage |
2 | Host Controller | |
3 | ||
4 | The Synopsys designware mobile storage host controller is used to interface | |
5 | a SoC with storage medium such as eMMC or SD/MMC cards. This file documents | |
6 | differences between the core Synopsys dw mshc controller properties described | |
7 | by synopsys-dw-mshc.txt and the properties used by the ZTE specific | |
8 | extensions to the Synopsys Designware Mobile Storage Host Controller. | |
9 | ||
10 | Required Properties: | |
11 | ||
12 | * compatible: should be | |
13 | - "zte,zx296718-dw-mshc": for ZX SoCs | |
14 | ||
15 | Example: | |
16 | ||
17 | mmc1: mmc@1110000 { | |
18 | compatible = "zte,zx296718-dw-mshc"; | |
19 | reg = <0x01110000 0x1000>; | |
20 | interrupts = <GIC_SPI 15 IRQ_TYPE_LEVEL_HIGH>; | |
21 | fifo-depth = <32>; | |
22 | data-addr = <0x200>; | |
23 | fifo-watermark-aligned; | |
24 | bus-width = <4>; | |
25 | clock-frequency = <50000000>; | |
26 | clocks = <&topcrm SD0_AHB>, <&topcrm SD0_WCLK>; | |
27 | clock-names = "biu", "ciu"; | |
