ohci-pci: add qemu quirk

2017-03-23T07:13:21+00:00

On a loaded virtualization host (dozen guests booting at the same time)
it may happen that the ohci controller emulation doesn't manage to do
timely frame processing, with the result that the io watchdog fires and
considers the controller being dead, even though it's only the emulation
being unusual slow due to the load peak.

So, add a quirk for qemu and don't use the watchdog in case we figure we
are running on emulated ohci.  The virtual ohci controller masquerades
as apple ohci controller, but we can identify it by subsystem id.

usb: add CONFIG_USB_PCI for system have both PCI HW and non-PCI based USB HW

2017-03-17T04:16:56+00:00

a lot of embeded system SOC (e.g. freescale T2080) have both
PCI and USB modules. But USB module is controlled by registers directly,
it have no relationship with PCI module.

when say N here it will not build PCI related code in USB driver.

lib/vsprintf.c: remove %Z support

2017-02-28T02:43:47+00:00

Now that %z is standartised in C99 there is no reason to support %Z.
Unlike %L it doesn't even make format strings smaller.

Use BUILD_BUG_ON in a couple ATM drivers.

In case anyone didn't notice lib/vsprintf.o is about half of SLUB which
is in my opinion is quite an achievement.  Hopefully this patch inspires
someone else to trim vsprintf.c more.

USB: OHCI: make ohci-da8xx a separate driver

2016-10-27T14:59:59+00:00

Separate the Davinci OHCI host controller driver from ohci-hcd
host code so that it can be built as a separate driver module.
This work is part of enabling multi-platform kernels on ARM

usb: increase ohci watchdog delay to 275 msec

2016-10-24T12:30:32+00:00

Increase ohci watchout delay to 275 ms. Previous delay was 250 ms
with 20 ms of slack, after removing slack time some ohci controllers don't
respond in time. Logs from systems with controllers that have the
issue would show "HcDoneHead not written back; disabled"

timers: Remove set_timer_slack() leftovers

2016-07-07T08:35:09+00:00

We now have implicit batching in the timer wheel. The slack API is no longer
used, so remove it.

USB: ohci-jz4740: Remove obsolete driver

2016-05-13T17:10:20+00:00

The ohci-platform driver can control the clock, while usb-nop-xceiv
as the PHY can control the vbus regulator. So this JZ4740-specific
glue is not needed anymore.

usb: ehci: ohci: fix bool assignments

2015-12-04T16:29:54+00:00

When assigning bool use true instead of 1. If declaring it as static and
it's false there's no need to initialize it, since static variables are
zeroed by default.

We should not be doing assignments within an if () block
so fix up the code to not do this.
