| 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 | 50dfe70 | 2009-09-22 16:45:14 -0700 | [diff] [blame] | 13 | - sdhci,wp-inverted : (optional) specifies that eSDHC controller |
| 14 | reports inverted write-protect state; |

| 16 | only handle 1-bit data transfers. |
