* 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>;
|
|
};
