* Freescale Enhanced Secure Digital Host Controller (eSDHC) for i.MX
The Enhanced Secure Digital Host Controller on Freescale i.MX family
provides an interface for MMC, SD, and SDIO types of memory cards.
This file documents differences between the core properties described
by mmc.txt and the properties used by the sdhci-esdhc-imx driver.
Required properties:
- compatible : Should be "fsl,<chip>-esdhc"
Optional properties:
- fsl,cd-controller : Indicate to use controller internal card detection
- fsl,wp-controller : Indicate to use controller internal write protection
Examples:
esdhc@70004000 {
compatible = "fsl,imx51-esdhc";
reg = <0x70004000 0x4000>;
interrupts = <1>;
fsl,cd-controller;
fsl,wp-controller;
};
esdhc@70008000 {
compatible = "fsl,imx51-esdhc";
reg = <0x70008000 0x4000>;
interrupts = <2>;
cd-gpios = <&gpio1 6 0>; /* GPIO1_6 */
wp-gpios = <&gpio1 5 0>; /* GPIO1_5 */
};
