The USB-IF CV compliance tester is getting stricter, and it would
be valid for it to fail a mass-storage device that accepts an
invalid USB_BULK_RESET_REQUEST request. Although it doesn't do
that yet, let's be proactive and fix that now.

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
f71648d73c (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.

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.

Properly triggering the reset wire is necessary with the ISP1761 used
on Terasic DE4 Altera-FPGA boards using a NIOS2 processor, for example.
This is an optional implementation for the OF binding only. The other
bindings just pass an invalid GPIO to the isp1760_register() routine.
Example, usage in DTS:
gpios = <&pio_isp1761rst_0 0 1>;
to point to a GPIO controller from within the ISP1761 node: GPIO 0, active low.

This patch (as1489) works around a hardware bug in MosChip EHCI
controllers. Evidently when one of these controllers increments the
frame-index register, it changes the three low-order bits (the
microframe counter) before changing the higher order bits (the frame
counter). If the register is read at just the wrong time, the value
obtained is too low by 8.
When the appropriate quirk flag is set, we work around this problem by
reading the frame-index register a second time if the first value's
three low-order bits are all 0. This gives the hardware a chance to
finish updating the register, yielding the correct value.
