* UCTL USB controller glue
Properties:
- compatible: "cavium,octeon-6335-uctl"
Compatibility with all cn6XXX SOCs.
- reg: The base address of the UCTL register bank.
- #address-cells: Must be <2>.
- #size-cells: Must be <2>.
- ranges: Empty to signify direct mapping of the children.
- refclk-frequency: A single cell containing the reference clock
frequency in Hz.
- refclk-type: A string describing the reference clock connection
either "crystal" or "external".
Example:
uctl@118006f000000 {
compatible = "cavium,octeon-6335-uctl";
reg = <0x11800 0x6f000000 0x0 0x100>;
ranges; /* Direct mapping */
#address-cells = <2>;
#size-cells = <2>;
/* 12MHz, 24MHz and 48MHz allowed */
refclk-frequency = <24000000>;
/* Either "crystal" or "external" */
refclk-type = "crystal";
