That's not true. They are also required for USB gadget controller
supported by the DWC2 gadget driver (formerly s3c-hsotg). Otherwise the
change makes sense to me.

Do you propose I amend just the patch description or also add a dependency on USB_DWC2 along with EHCI and OHCI. I do not have anything to test this. Based on your input I will re-spin the patch.

Personally, I think that it would be good to amend the commit message and add a dependency on USB_DWC2. :-) Thank you.

Since the USB 2.0 PHYs are required only with EHCI/OHCI USB drivers, make it depend on them and default to ARCH_EXYNOS as they are meant for Exynos platforms. Also, make the sub-drivers silent options enabling them based on the SoC platforms that they are meant to work with. This will make life easier for end users who do not have any way knowing the dependencies.
