1 | * Freescale Enhanced Secure Digital Host Controller (eSDHC) for i.MX |
| 2 | ||
| 3 | The Enhanced Secure Digital Host Controller on Freescale i.MX family | |
| 4 | provides an interface for MMC, SD, and SDIO types of memory cards. | |
| 5 | ||
| 6 | Required properties: | |
| 7 | - compatible : Should be "fsl,<chip>-esdhc" | |
| 8 | - reg : Should contain eSDHC registers location and length | |
| 9 | - interrupts : Should contain eSDHC interrupt | |
| 10 | ||
| 11 | Optional properties: | |
| 7f217794 | 12 | - non-removable : Indicate the card is wired to host permanently |
| abfafc2d SG |
13 | - fsl,cd-internal : Indicate to use controller internal card detection |
| 14 | - fsl,wp-internal : Indicate to use controller internal write protection | |
| 15 | - cd-gpios : Specify GPIOs for card detection | |
| 16 | - wp-gpios : Specify GPIOs for write protection | |
| 17 | ||
| 18 | Examples: | |
| 19 | ||
| 20 | esdhc@70004000 { | |
| 21 | compatible = "fsl,imx51-esdhc"; | |
| 22 | reg = <0x70004000 0x4000>; | |
| 23 | interrupts = <1>; | |
| 24 | fsl,cd-internal; | |
| 25 | fsl,wp-internal; | |
| 26 | }; | |

| 29 | compatible = "fsl,imx51-esdhc"; | |
| 30 | reg = <0x70008000 0x4000>; | |
| 31 | interrupts = <2>; | |
