This doesn't apply as
commit 7b8ef22ea547b80475ac7feab06fb15e0fc143d8
usb: xhci: plat: Add USB phy support
changed xhci-plat.c since.
I rebased it, and the changed version is sitting in the for-usb-next branch in:
git://git.kernel.org/pub/scm/linux/kernel/git/mnyman/xhci.git
But it appeared to me that usb_add_hcd() and usb_remove_hcd() will also
call phy init and remove functions. As the order how hcds are created and added
would change I'd need some more eyes on this to see if it will cause regression.
Or maybe in the best case we could get rid of the "Add USB phy support" patch as
we will call xhci_add_hcd() for the first hcd much later, and it could maybe init
the phy for us?
I don't have a board that enumerates xhci using xhci-plat.c myself.
