Here is clock for usb2phy.  CLK_APMU_USB3_PORTB_BUS is clock for USB3 PORTB. CLK_APMU_USB3_PORTC_BUS is clock for USB3 PORTC.

Please note: usb3d_u2phy also use CLK_APMU_USB2_BUS.

                usb3d_u2phy: phy@81b00000 {
                        compatible = "spacemit,k3-usb2-phy";
                        reg = <0x0 0x81b00000 0x0 0x200>;
                        clocks = <&syscon_apmu CLK_APMU_USB2_BUS>;
                        #phy-cells = <0>;
                        status = "disabled";
                };
