|  | * Freescale MXS MMC controller | 
|  |  | 
|  | The Freescale MXS Synchronous Serial Ports (SSP) can act as a MMC controller | 
|  | to support MMC, SD, and SDIO types of memory cards. | 
|  |  | 
|  | This file documents differences between the core properties in mmc.txt | 
|  | and the properties used by the mxsmmc driver. | 
|  |  | 
|  | Required properties: | 
|  | - compatible: Should be "fsl,<chip>-mmc".  The supported chips include | 
|  | imx23 and imx28. | 
|  | - interrupts: Should contain ERROR interrupt number | 
|  | - dmas: DMA specifier, consisting of a phandle to DMA controller node | 
|  | and SSP DMA channel ID. | 
|  | Refer to dma.txt and fsl-mxs-dma.txt for details. | 
|  | - dma-names: Must be "rx-tx". | 
|  |  | 
|  | Examples: | 
|  |  | 
|  | ssp0: ssp@80010000 { | 
|  | compatible = "fsl,imx28-mmc"; | 
|  | reg = <0x80010000 2000>; | 
|  | interrupts = <96>; | 
|  | dmas = <&dma_apbh 0>; | 
|  | dma-names = "rx-tx"; | 
|  | bus-width = <8>; | 
|  | }; |
