| 2 | |
| 3 | Required properties: |
| 4 | - compatible : "qcom,sdhci-msm-v4" |
| 5 | - reg: Base address and length of registers: |
| 6 | - Host controller registers (SDHCI) |
| 7 | - SD Core registers |
| 8 | - clock: interface clock (must accept SD bus clock as a frequency) |
| 9 | |
| 10 | Optional properties: |
| 11 | - index: If there is more than one controller - controller index (required |
| 12 | by generic SDHCI code). |
| 13 | - bus_width: Width of SD/eMMC bus (default 4) |
| 14 | - clock-frequency: Frequency of SD/eMMC bus (default 400 kHz) |
| 15 | |
| 16 | Example: |
| 17 | |
| 18 | sdhci@07864000 { |
| 19 | compatible = "qcom,sdhci-msm-v4"; |
| 20 | reg = <0x7864900 0x11c 0x7864000 0x800>; |
| 21 | index = <0x1>; |
| 22 | bus-width = <0x4>; |
| 23 | clock = <&clkc 1>; |
| 24 | clock-frequency = <200000000>; |
| 25 | }; |
