Russell King 9480e307cd [PATCH] DRIVER MODEL: Get rid of the obsolete tri-level suspend/resume callbacks
In PM v1, all devices were called at SUSPEND_DISABLE level.  Then
all devices were called at SUSPEND_SAVE_STATE level, and finally
SUSPEND_POWER_DOWN level.  However, with PM v2, to maintain
compatibility for platform devices, I arranged for the PM v2
suspend/resume callbacks to call the old PM v1 suspend/resume
callbacks three times with each level in order so that existing
drivers continued to work.

Since this is obsolete infrastructure which is no longer necessary,
we can remove it.  Here's an (untested) patch to do exactly that.

Olav Kongas e9b765decf [PATCH] isp116x-hcd: fix handling of short transfers
Increased use of scatter-gather by usb-storage driver after 2.6.13 has
exposed a buggy codepath in isp116x-hcd, which was probably never
visited before: bug happened only for those urbs, for which
URB_SHORT_NOT_OK was set AND short transfer occurred.

The fix attached was tested in 2 ways: (a) it fixed failing
initialization of a flash drive with an embedded hub; (b) the fix was
tested with 'usbtest' against a modified g_zero driver (on top of
net2280), which generated short bulk IN transfers of various lengths
including multiples and non-multiples of max_packet_length.

Olav Kongas 9a57116bc9 [PATCH] USB: Switch isp116x-hcd over to root hub interrupt
Switch isp116x-hcd over from root hub polling to interrupt.  This change closes
also a race that was present with the old polling scheme: status polling could
happen in a time window, where root hub status bits were not stable.

Olav Kongas f8d23d3098 [PATCH] USB: isp116x-hcd: remove clock() and reset()
This patch removes support for user-provided platform-specific hardware reset
and clock starting/stopping functions. Hardware reset was needed earlier as
getting the software reset working was tricky due to the lack of documentation.
Recently, a number of people using isp116x have said the software reset is
working for them.

I haven't heard of anybody using the clock starting/stopping.

the typecasting of mem_flags argument for kcalloc; this will
be addressed in a later patch.

Olav Kongas 589a0083a3 [PATCH] USB: Fix oops at rmmod after failed probe in isp116x-hcd
This patch fixes an oops triggered at rmmod of isp116x-hcd
after the probe() has failed.

Also, it extends the error message printed, if the driver
cannot detect "Chip's Clock Ready" after a software reset.
As Ian Campbell recently reported, this happens if the
chip's H_WAKEUP pin is not pulled low during software reset.
Several people have already had this issue, hence the update
to the error message.

Also, extend the error message about the failed clock
detection after the software reset.

Olav Kongas 4808a1c026 [PATCH] USB: Add isp116x-hcd USB host controller driver
This patch provides an "isp116x-hcd" driver for Philips'
ISP1160/ISP1161 USB host controllers.

The driver:
 - is relatively small, meant for use on embedded platforms.
 - runs usbtests 1-14 without problems for days.
 - has been in use by 6-7 different people on ARM and PPC platforms,
   running a range of devices including USB hubs.
 - supports suspend/resume of both the platform device and the root hub;
   supports remote wakeup of the root hub (but NOT the platform device)
   by USB devices.
 - does NOT support ISO transfers (nobody has asked for them).
 - is PIO-only.
