Hi Dmitry,
Semi-random suggestion, but could you please try using
clk_regmap_phy_mux/clk_regmap_phy_mux_ops for USB pipe clk src?
Which specific clock are you refering to? I'm not very familiar with
those, in the device tree I'm seeing "pipe" clocks for usb_0 and usb_1
phys, but not for usb_2, which is the one that's causing issues.
