Why is the SoC / compatible information not coming from DT instead ? Why
is the driver polluted by more ifdefs ?

Because this platform doesn't have DM clock driver yet. This code will
be removed once this driver is implemented.

You don't need DM clock driver, you can check the compatible string I
think ?

Yes or driver_data, if we wanted to get rid of other #Ifdef on the file

OK, I'll change it to use driver_data.

extra_usb_gate_mask isn't shifted later and thus
CCM_USB_CTRL_OHCI0_CLK and CCM_USB_CTRL_OHCI1_CLK will be enabled for
phy 1 on A64.

Where are you checking phy 1? and you still using
CCM_USB_CTRL_OHCI0_CLK not OHCI1_CLK

phys is PHY index, usb_gate_mask is shifted to PHY index later - thus
it'll be CCM_USB_CTRL_OHCI1_CLK,
extra_usb_gate_mask is not - it'll remain CCM_USB_CTRL_OHCI0_CLK.
Since A64 has only 2 USB controllers that covers it.
