Kernel-4.18.0-80.el8_uctl

• 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”;
