usb: Make core allocate resources per PCI-device. ...
Introduce the notion of a PCI device that may be associated with more than
one USB host controller driver (struct usb_hcd). This patch is the start
of the work to separate the xHCI host controller into two roothubs: a USB
3.0 roothub with SuperSpeed-only ports, and a USB 2.0 roothub with
HS/FS/LS ports.
One usb_hcd structure is designated to be the "primary HCD", and a pointer
is added to the usb_hcd structure to keep track of that. A new function
call, usb_hcd_is_primary_hcd() is added to check whether the USB hcd is
marked as the primary HCD (or if it is not part of a roothub pair). To
allow the USB core and xHCI driver to access either roothub in a pair, a
"shared_hcd" pointer is added to the usb_hcd structure.
Add a new function, usb_create_shared_hcd(), that does roothub allocation
for paired roothubs. It will act just like usb_create_hcd() did if the
primary_hcd pointer argument is NULL. If it is passed a non-NULL
primary_hcd pointer, it sets usb_hcd->shared_hcd and usb_hcd->primary_hcd
fields. It will also skip the bandwidth_mutex allocation, and set the
secondary hcd's bandwidth_mutex pointer to the primary HCD's mutex.
IRQs are only allocated once for the primary roothub.
Introduce a new usb_hcd driver flag that indicates the host controller
driver wants to create two roothubs. If the HCD_SHARED flag is set, then
the USB core PCI probe methods will allocate a second roothub, and make
sure that second roothub gets freed during rmmod and in initialization
error paths.
When usb_hc_died() is called with the primary HCD, make sure that any
roothubs that share that host controller are also marked as being dead.
