Missing USB clock for BCM2835

i'm working on Raspberry Pi Zero support (incl. OTG / Gadget). I wanted to add
the missing clock control for DWC2 , but i didn't find a matching clock in
the clock tree.
The BCM2835 clk driver contains the define A2W_XOSC_CTRL_USB_ENABLE, but no
separate registers. So i assume USB clock is a child of xosc only with a gate
and a fixed frequency of 480 MHz.
Is it correct?
