| * 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. |
| |
| Required properties: |
| - compatible: Should be "fsl,<chip>-mmc". The supported chips include |
| imx23 and imx28. |
| - reg: Should contain registers location and length |
| - interrupts: Should contain ERROR and DMA interrupts |
| - fsl,ssp-dma-channel: APBH DMA channel for the SSP |
| - bus-width: Number of data lines, can be <1>, <4>, or <8> |
| |
| Optional properties: |
| - wp-gpios: Specify GPIOs for write protection |
| |
| Examples: |
| |
| ssp0: ssp@80010000 { |
| compatible = "fsl,imx28-mmc"; |
| reg = <0x80010000 2000>; |
| interrupts = <96 82>; |
| fsl,ssp-dma-channel = <0>; |
| bus-width = <8>; |
| }; |
