* 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>;
|
|
};
