Generally this works fine but I wouldn't recommend this approach if:
- there's some required wait time after the clock has been enabled
(see phy_meson_g12a_usb2_init - there's already some required wait
time after triggering the reset)
- clock gating (for power saving) is needed when the dwc3 driver is
unloaded by the PHY driver is not
In this case: just manually manage the clock in phy_meson_g12a_usb2_{init,exit}
Best regards,
Martin
