Re: [PATCH] drivers/usb/dwc3: Set PHY ready after soft reset done

It's more safe to set PHY ready after soft reset done

Let's consider a test case like this:
I have a usb PHY which don't need SW initial before access
it, But i have a wrong PHY clock default setting in PHY
register which means PHY is not ready in fact.
in dwc3_core_init, dwc3_core_get_phy will return 0 despite
usb get PHYs with return -ENODEV, and set phys_ready=true

your PHY driver shouldn't return -ENODEV here. Why are you returning
-ENODEV? The PHY isn't ready but it _does_ exist.
