can you please provide a rationale why you need manual control over that 
intermediate clock?

The two usbphys seem to use the  clk_usb2phyX_ref clocks, generate the 480m 
clocks, but do not seem to need the clk_usbphyX_480m_src gates.

The clk_usbphyX_480m_src clocks on the other hand only lead to the 
clk_usbphy_480m mux, so I'd like some explanation on what you want to achieve 
here :-)


Thanks
Heiko
