| * 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>; |
| }; |
