*	USB: xhci: Fix finding extended capabilities registers	Edward Shao	2010-03-02	1	-2/+5
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	According "5.3.6 Capability Parameters (HCCPARAMS)" of xHCI rev0.96 spec, value of xECP register indicates a relative offset, in 32-bit words, from Base to the beginning of the first extended capability. The wrong calculation will cause BIOS handoff fail (not handoff from BIOS) in some platform with BIOS USB legacy sup support.

*	USB: xhci: Support xHCI host controllers and USB 3.0 devices.	Sarah Sharp	2009-06-15	1	-0/+145
	This is the first of many patches to add support for USB 3.0 devices and the hardware that implements the eXtensible Host Controller Interface (xHCI) 0.95 specification. This specification is not yet publicly available, but companies can receive a copy by becoming an xHCI Contributor (see http://www.intel.com/technology/usb/xhcispec.htm). No xHCI hardware has made it onto the market yet, but these patches have been tested under the Fresco Logic host controller prototype. This patch adds the xHCI register sets, which are grouped into five sets: - Generic PCI registers - Host controller "capabilities" registers (cap_regs) short - Host controller "operational" registers (op_regs) - Host controller "runtime" registers (run_regs) - Host controller "doorbell" registers These some of these registers may be virtualized if the Linux driver is running under a VM. Virtualization has not been tested for this patch. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
