USB: Update last_busy time after autosuspend fails

2011-11-04T21:28:14+00:00

Originally, the runtime PM core would send an idle notification
whenever a suspend attempt failed.  The idle callback routine could
then schedule a delayed suspend for some time later.

However this behavior was changed by commit
f71648d73c1650b8b4aceb3856bebbde6daa3b86 (PM / Runtime: Remove idle
notification after failing suspend).  No notifications were sent, and
there was no clear mechanism to retry failed suspends.

This caused problems for the usbhid driver, because it fails
autosuspend attempts as long as a key is being held down.  A companion
patch changes the PM core's behavior, but we also need to change the
USB core.  In particular, this patch (as1493) updates the device's
last_busy time when an autosuspend fails, so that the PM core will
retry the autosuspend in the future when the delay time expires
again.

usb, xhci: Clear warm reset change event during init

2011-11-04T19:34:40+00:00

I noticed on my Panther Point system that I wasn't getting hotplug events
for my usb3.0 disk on a usb3 port.  I tracked it down to the fact that the
system had the warm reset change bit still set.  This seemed to block future
events from being received, including a hotplug event.

Clearing this bit during initialization allowed the hotplug event to be
received and the disk to be recognized correctly.

This patch should be backported to kernels as old as 2.6.39.

usb: Add export.h for EXPORT_SYMBOL/THIS_MODULE where needed

2011-10-31T23:31:25+00:00

With module.h being implicitly everywhere via device.h, the absence
of explicitly including something for EXPORT_SYMBOL went unnoticed.
Since we are heading to fix things up and clean module.h from the
device.h file, we need to explicitly include these files now.

Use the lightweight version of the header that has just THIS_MODULE
and EXPORT_SYMBOL variants.

xHCI/USB: Make xHCI driver have a BOS descriptor.

2011-10-18T20:42:06+00:00

To add USB 3.0 link power management (LPM), we need to know what the U1
and U2 exit latencies are for the xHCI host controller.  External USB 3.0
hubs report these values through the SuperSpeed Capabilities descriptor in
the BOS descriptor.  Make the USB 3.0 roothub for the xHCI host behave
like an external hub and return the BOS descriptors.

The U1 and U2 exit latencies will vary across each host controller, so we
need to dynamically fill those values in by reading the exit latencies out
of the xHC registers.  Make the roothub code in the USB core handle
hub_control() returning the length of the data copied.
