This is the fourth revision of the patchset to add USB 3.0 hub support
to the USB core, and split the xHCI roothubs into two hubs: a USB 2.0
roothub that handles LS/FS/HS devices and a USB 3.0 roothub that handles
SuperSpeed devices.
Updated patches from RFC v3:
usb: Make USB 3.0 roothub have a SS EP comp descriptor.
- Remove unnecessary extra column
usb: Make core allocate resources per PCI-device.
- Free bandwidth_mutex for the primary HCD only
- Make sure usb_hc_died() handles both the primary and secondary HCD
USB: Set usb_hcd->state and flags for shared roothubs.
- Update the patch based on Alan's patch to clean up hcd->state
xhci: Register second xHCI roothub.
- Set hcd->has_tt and hcd->speed for the USB 2.0 roothub in the xHCI
driver. This removes the last of the dependencies between the xHCI
driver and the USB PCI host probe function.
- Remove old reference to hcd->bcdUSB
New patches for RFC v4:
xhci: Return canceled URBs immediately when host is halted.
- This patch, combined with the updated USB core PCI resources patch,
gets rid of the oops I was seeing when I unload the xHCI driver
when a mouse is plugged in.
I think this addresses all the feedback I got on Monday. Unless anyone
has any serious objections, I'll submit these patches to Greg KH
tomorrow.
