| * 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-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 |
| |
| Examples: |
| |
| esdhc@70004000 { |
| compatible = "fsl,imx51-esdhc"; |
| reg = <0x70004000 0x4000>; |
| interrupts = <1>; |
| fsl,cd-internal; |
| fsl,wp-internal; |
| }; |
| |
| 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 */ |
| }; |
