The platform device resources are never used vainly. And remember that if PHY doesn't get registered, OHCI/EHCI won't get probed successfully either -- mind the usb_power_on() platform method.
? Could you please teach me who/how/when free resource memory which was kmemdup'ed by platform_device_add_xxx() (and kmalloc'ed dma_mask) on platform_device_register_full() ??
I don't think there's a need to free them. The EHCI/OHCI devices are always there after all.
ohci/ehci and phy should be registered in same time/function.
I just copied your approach from the R8A7779 code.
Ahh, yes, indeed
Moreover, from our prior testing, I'm afraid registering USB PHY and EHCI/OHCI in one function wouldn't work. Unless maybe if it's done from the init_late() machine's method...
