- * 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.
- Required properties:
- - compatible : Should be "fsl,<chip>-esdhc"
- - reg : Should contain eSDHC registers location and length
- - interrupts : Should contain eSDHC interrupt
- Optional properties:
- - fsl,card-wired : Indicate the card is wired to host permanently
- - fsl,cd-controller : Indicate to use controller internal card detection
- - fsl,wp-controller : Indicate to use controller internal write protection
- - cd-gpios : Specify GPIOs for card detection
- - wp-gpios : Specify GPIOs for 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 = <&gpio0 6 0>; /* GPIO1_6 */
- wp-gpios = <&gpio0 5 0>; /* GPIO1_5 */
- };
