One more thing: why is the USB2 PHY relevant to the OHCI controller? And
if it is relevant, why isn't there a PHY phandle for it in
usb_host0_ohci and usb_host1_ohci in rk3399.dtsi? As it stands, your
patch is hacking in USB2 clock references for OHCI, but you're not
actually managing the PHY there at all. Seems like you'd want to do
all-or-nothing if there's a functional dependency between the OHCI
controllers and the USB2 PHYs.
