| 2 | |
| 3 | Properties: |
| 4 | - compatible: "cavium,octeon-6335-uctl" |
| 5 | |
| 6 | Compatibility with all cn6XXX SOCs. |
| 7 | |
| 8 | - reg: The base address of the UCTL register bank. |
| 9 | |
| 10 | - #address-cells: Must be <2>. |
| 11 | |
| 12 | - #size-cells: Must be <2>. |
| 13 | |
| 14 | - ranges: Empty to signify direct mapping of the children. |
| 15 | |
| 16 | - refclk-frequency: A single cell containing the reference clock |
| 17 | frequency in Hz. |
| 18 | |
| 19 | - refclk-type: A string describing the reference clock connection |
| 20 | either "crystal" or "external". |
