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"
-- reg : Should contain eSDHC registers location and length
-- interrupts : Should contain eSDHC interrupt
Optional properties:
-- non-removable : Indicate the card is wired to host permanently
-- fsl,cd-internal : Indicate to use controller internal card detection
-- fsl,wp-internal : Indicate to use controller internal write protection
-- cd-gpios : Specify GPIOs for card detection
-- wp-gpios : Specify GPIOs for write protection
+- fsl,cd-controller : Indicate to use controller internal card detection
+- fsl,wp-controller : Indicate to use controller internal write protection
Examples:
compatible = "fsl,imx51-esdhc";
reg = <0x70004000 0x4000>;
interrupts = <1>;
- fsl,cd-internal;
- fsl,wp-internal;
+ fsl,cd-controller;
+ fsl,wp-controller;
