uhci-hcd: fix list access bug

2006-09-08T21:51:39+00:00

When skipping to the last TD of an URB, go to the _last_ entry in the
list instead of the _first_ entry (as780).  This fixes Bugzilla #6747 and
possibly others.

UHCI: Fix handling of short last packet

2006-08-07T03:52:14+00:00

This patch (as753) fixes the way uhci-hcd handles a short packet when it
is the last packet of an URB.  Right now the driver handles short packets
the same no matter when they occur.  However, the controller stops
transferring packets when the short packet is not the last one (otherwise
it would be reading beyond the end of the device's data) and needs to be
restarted, whereas no such need occurs when the short packet is the last
one.

The result of the bug is that USB endpoint queues experience intermittent
hangs, a regression in 2.6.17 with respect to earlier kernels.  The bug
was raised in Bugzilla #6752 and this patch fixed it.

[ARM] 3547/1: PXA-OHCI: Allow platforms to specify a power budget

2006-06-08T21:44:07+00:00

Patch from Richard Purdie

Add a power budget variable to the PXA OHCI platform data and add a
default value for the spitz platform(s) which prevents known failures
with certain USB devices.

[PATCH] USB: fix bug in ohci-hcd.c ohci_restart()

2006-05-09T06:43:54+00:00

A loop on a power-lost resume path used the wrong index.
I suspect khubd has been working around such bugs.

[PATCH] USB: Use new PCI_CLASS_SERIAL_USB_* defines

2006-04-27T17:28:59+00:00

We could use the recently added PCI_CLASS_SERIAL_USB_UHCI,
PCI_CLASS_SERIAL_USB_OHCI and PCI_CLASS_SERIAL_USB_EHCI defines in
more places, for slightly shorter and clearer code.

[PATCH] USB: S3C2410: use clk_enable() to ensure 48MHz to OHCI core

2006-04-14T18:12:26+00:00

Get the "usb-bus" clock and ensure it is enabled
when the OHCI core is in use.

It seems that a few bootloaders do not enable the
UPLL at startup, which stops the OHCI core having
a 48MHz bus clock. The improvements to the clock
framework for the s3c24xx now allow the USB PLL
to be started and stopped when being used.

[PATCH] USB: UHCI: don't track suspended ports

2006-04-14T18:12:26+00:00

Someone recently posted a bug report where it turned out that uhci-hcd
was disagreeing with the UHCI controller over whether or not a port was
suspended: The driver thought it wasn't and the hardware thought it was.
This patch (as665) fixes the problem and simplifies the driver by
removing the internal state-tracking completely.  Now the driver just
asks the hardware whether a port is suspended.

[PATCH] USB: at91 usb driver supend/resume fixes

2006-04-14T18:12:25+00:00

AT91: the two USB drivers (OHCI, UDC) got out of sync with various
usbcore and driver model PM updates; fix.

Also minor fixes to ohci:  whitespace/style, MODULE_ALIAS so coldplug works
using /sys/.../modalias, and turn off _both_ clocks during suspend.
