Now that we have common bindings for MMC, rewrite the individual bindings to inherit from mmc.txt and describe their differences. Acked-by: Stephen Warren <swarren@wwwdotorg.org> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Chris Ball <cjb@laptop.org>

* 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 and DMA interrupts
|
|
- fsl,ssp-dma-channel: APBH DMA channel for the SSP
|
|
|
|
Examples:
|
|
|
|
ssp0: ssp@80010000 {
|
|
compatible = "fsl,imx28-mmc";
|
|
reg = <0x80010000 2000>;
|
|
interrupts = <96 82>;
|
|
fsl,ssp-dma-channel = <0>;
|
|
bus-width = <8>;
|
|
};
