| 2 | |
| 3 | The Freescale MXS Synchronous Serial Ports (SSP) can act as a MMC controller |
| 4 | to support MMC, SD, and SDIO types of memory cards. |
| 5 | |
| 6 | Required properties: |
| 7 | - compatible: Should be "fsl,<chip>-mmc". The supported chips include |
| 8 | imx23 and imx28. |
| 9 | - reg: Should contain registers location and length |
| 10 | - interrupts: Should contain ERROR and DMA interrupts |
| 11 | - fsl,ssp-dma-channel: APBH DMA channel for the SSP |
| 12 | - bus-width: Number of data lines, can be <1>, <4>, or <8> |
| 13 | |
| 14 | Optional properties: |
| 15 | - wp-gpios: Specify GPIOs for write protection |
| 16 | |
| 17 | Examples: |
| 18 | |
| 19 | ssp0: ssp@80010000 { |
| 20 | compatible = "fsl,imx28-mmc"; |
| 21 | reg = <0x80010000 2000>; |
| 22 | interrupts = <96 82>; |
| 23 | fsl,ssp-dma-channel = <0>; |
| 24 | bus-width = <8>; |
| 25 | }; |
