| 2 | |
| 3 | The Enhanced Secure Digital Host Controller provides an interface |
| 4 | for MMC, SD, and SDIO types of memory cards. |

| Anton Vorontsov | 34bcda6 | 2009-02-05 22:04:47 +0300 | [diff] [blame] | 9 | - reg : should contain eSDHC registers location and length. |
| 10 | - interrupts : should contain eSDHC interrupt. |
| 11 | - interrupt-parent : interrupt source phandle. |
| 12 | - clock-frequency : specifies eSDHC base clock frequency. |
| Anton Vorontsov | 5fe23c7 | 2009-06-18 00:14:08 +0400 | [diff] [blame^] | 13 | - sdhci,1-bit-only : (optional) specifies that a controller can |
| 14 | only handle 1-bit data transfers. |
