Now that it's in use on other boards, a bug in the original code needs fixing.

There is no need for the PXA27x OHCI to set usb power during init, since
the hub driver in usbcore handles that. Those platform-specific power
control functions are also incorrect, and should therefore be removed.

Add a check to clear the OTG pin hold bit until such times OTG is
properly implemented.

Some OHCI implementations have differences in the way the NDP register
(in roothub_a) reports the number of ports present. This patch allows the
platform specific code to optionally supply the number of ports. The
driver just reads the value at init (if not supplied) instead of reading
it every time its needed (except for an AMD756 bug workaround).

It also sets the value correctly for the ARM pxa27x architecture.

Evidently there are some boards which care a lot about this, but
as a rule it's been hard to notice.

OHCI_INTR_RD wasn't always cleared in the ohci irq handler.  On some
systems this means certain remote wakeup scenarios could seem to hang
(in an interrupt storm, RD never clearing).

Routine cases like handoff-to-companion shouldn't trigger diagnostics.
This gets rid of some recently added log spamming.  It's routine for
hub_port_wait_reset() to return -ENOTCONN to indicate handoff from
highspeed hubs to companions, so an error message is incorrect.

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 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.

This is the same patch that went into i386 just before 2.6.13
came out.  I still can't build 64-bit user apps, so I tested
with program (see below) in 32-bit mode on 64-bit kernel:

Before:

	$ fpsig
	handler: nr = 8, si = 0x0804bc90, vuc = 0x0804bd10
	handler: altstack is at 0x0804b000, ebp = 0x0804bc7c
	handler: si_signo = 8, si_errno = 0, si_code = 0 [unknown]
	handler: fpu cwd = 0xb40, fpu swd = 0xbaa0
	handler: i387 unmasked precision exception, rounded up

After:

	$ fpsig
	handler: nr = 8, si = 0x0804bc90, vuc = 0x0804bd10
	handler: altstack is at 0x0804b000, ebp = 0x0804bc7c
	handler: si_signo = 8, si_errno = 0, si_code = 6 [inexact result]
