Hey Simon,

I've picked this commit because of what I saw in f879fc32a
("usb: host: xhci-rcar: Avoid long wait in xhci_reset()").

>From my understanding of that change, we added a dependency on ARCH_RENESAS
for USB_XHCI_PLATFORM, but since USB_XHCI_RCAR depended on ARCH_SHMOBILE that
would cause silly errors for kconfig and would probably confuse users.

Rather than changing it to a ARCH_SHMOBILE dependency, I've preferred
to pull in f879fc32a to keep the stable tree more aligned with upstream
and possibly prevent any future backporting errors for new commits that
add ARCH_RENESAS dependencies.

If you don't agree with that approach I can change that to a ARCH_SHMOBILE
dependency and remove this commit, or take any other approach you think
is better?


Thanks,
Sasha
