- * 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>;
- };
