| 2 | |
| 3 | The Enhanced Secure Digital Host Controller provides an interface |
| 4 | for MMC, SD, and SDIO types of memory cards. |
| 5 | |
| 6 | Required properties: |
| 7 | - compatible : should be |
| 8 | "fsl,<chip>-esdhc", "fsl,mpc8379-esdhc" for MPC83xx processors. |
| 9 | "fsl,<chip>-esdhc", "fsl,mpc8536-esdhc" for MPC85xx processors. |
| 10 | - reg : should contain eSDHC registers location and length. |
| 11 | - interrupts : should contain eSDHC interrupt. |
| 12 | - interrupt-parent : interrupt source phandle. |
| 13 | - clock-frequency : specifies eSDHC base clock frequency. |
| 14 | |
| 15 | Example: |
| 16 | |
| 17 | sdhci@2e000 { |
| 18 | compatible = "fsl,mpc8378-esdhc", "fsl,mpc8379-esdhc"; |
| 19 | reg = <0x2e000 0x1000>; |
| 20 | interrupts = <42 0x8>; |
| 21 | interrupt-parent = <&ipic>; |
| 22 | /* Filled in by U-Boot */ |
| 23 | clock-frequency = <0>; |
| 24 | }; |
