One change may improve some S1 or S3 resume cases, and the other
seems mostly to explain some strange state "lsusb" would show.
Two fixes:
- On resume, don't think about resuming any unpowered port, or
resetting any port with OWNER set to the OHCI/UHCI companion.
This will make some S1 and S3 resume scenarios work better.
- PORT_CSC was not being cleared correctly in ehci_hub_status_data.
This was visible at least through current versions of "lsusb",
and might have caused some other hub related strangeness.
The fix addresses all three write-to-clear bits, using the same
approach that UHCI happens to use: a mask of bits that are
cleared in most writes to that port status register.
Original patch seems to have been from from William.Morrow@amd.com
and this version (from David) finishes the write-to-clear changes.

This patch (as558) removes from the UHCI driver a kernel timer used for

done during normal root-hub polling; it doesn't need a separate timer.

This patch (as549) introduces two small changes in the HCD glue layer.

This is a driver for the USB touchpad which can be found on post-February 2005
Apple PowerBooks.
This driver is derived from Johannes Berg's appletrackpad driver [1],
but it has been improved in some areas:
* appletouch is a full kernel driver, no userspace program is necessary
* appletouch can be interfaced with the synaptics X11 driver[2], in order
to have touchpad acceleration, scrolling, two/three finger tap, etc.
This driver has been tested by the readers of the 'debian-powerpc' mailing
list for a few weeks now and I believe it is now ready for inclusion into the
mainline kernel.
Credits go to Johannes Berg for reverse-engineering the touchpad protocol,
Frank Arnold for further improvements, and Alex Harper for some additional
information about the inner workings of the touchpad sensors.

here is a new and extended version of the sisusbvga (previously: sisusb)
driver. The patch is against 2.6.13 and updates the driver to version 0.0.8.
Additions include complete VGA/EGA text console support and a build-in
display mode infrastructure for userland applications that don't know
about the graphics internals.
Fixes include some BE/LE issues and a get/put_dev bug in the previous
version.
Other changes include a change of the module name from "sisusb" to
"sisusbvga". The previous one was too generic IMHO.
Please note that the patch also affects the Makefile in
drivers/video/console as the driver requires the VGA 8x16 font in case
the text console part is selected.
Heavily tested, as usual. Please apply.
One thing though: I already prepared for removal of the "mode" field and
the changed "name" field in the usb_class_driver structure. This will
perhaps need some refinement depending on whether you/Linus merge the
respective core changes before or after 2.6.14.

Reported by: Manuel Lauss <mano@roarinelk.homelinux.net>
He was getting random initial video modes depending on the kernel
configuration. His option line includes 'extvga'.
The i810fb documentation describes the option 'extvga', however the
driver accepts 'ext_vga'. Besides 'extvga' being ignored by i810fb,
it also confuses the option parser of i810fb and assigns 'extvga' to
'mode_option'. This leads to an incorrect video mode at boot time.
