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”;
