Netwinder was using gpio_xxx names which could clash with the GPIO
layer. Add a 'nw_' prefix to ensure that these remain separate.

The Orion ehci driver serves the Orion, kirkwood and DD Soc families.
Since each of those integrate a different USB phy we should have the
ability to use few initialization sequences or to leave the boot loader
phy settings as is.

The optimal change would be to move the AC97 register definitions into
the AC97 driver, unfortunately, the registers are shared between several

Fix module removal bugs of i82875p_edac. Also i82975x_edac code seems to
have the same module removal bugs as in i82875p_edac.
The problems were:
1. In module removal i82875p_remove_one() is never called.
Variable i82875p_registered is newer changed from 1, which
guarantees i82875p_remove_one() is not called (and even if it were
called, it would be called in wrong order).
As a result, the edac_mc workque is not stopped and keeps probing.
If kernel debugging options are not enabled, user may not notice
anything going wrong.
if debugging options are enabled and I do "rmmod i82875p_edac", I
get:
edac debug: edac_pci_workq_function() checking
BUG: unable to handle kernel paging request at f882d16f
...
call trace:

[<c02367ce>] ? kthread+0x0/0x61
[<c0204587>] ? kernel_thread_helper+0x7/0x10
Fix for this is to get rid of needles variable i82875p_registered
altogether and run i82875p_remove_one() *before*
pci_unregister_driver().
2. edac_mc_del_mc() uses mci after freeing mci
edac_mc_del_mc() calls calls edac_remove_sysfs_mci_device(). The
kobject refcount of mci drops to 0 and mci is freed. After this
mci is accessed via debug print and i82875p_remove_one() still
uses mci->pvt and tries to free mci again with edac_mc_free().
The fix for this is add kobject_get(&mci->edac_mci_kobj) after
edac_mc_alloc(). Then the mci is still available after returning
from edac_mc_del_mc() with refcount 1, and mci->pvt is still
available. When i82875p_remove_one() finally calls edac_mc_free(),
this will cause kobject_put() and mci is released properly.

When I do "modprobe i82875p_edac" on my Asus P4C800 MB on kernels 2.6.26
or later, the module load fails due to BAR 0 collision. On 2.6.25 the
module loads just fine.
The overflow device on the MB seems to be hidden and its resources are not
allocated at normal PCI bus init. Log shows the missing resource problem:
EDAC DEBUG: i82875p_probe1()
PCI: 0000:00:06.0 reg 10 32bit mmio: [fecf0000, fecf0fff]
pci 0000:00:06.0: device not available because of BAR 0
[0xfecf0000-0xfecf0fff] collisions
EDAC i82875p: i82875p_setup_overfl_dev(): Failed to enable overflow
device
The patch below fixes this by calling pci_bus_assign_resources() after
the overflow device is revealed and added to the bus. With this patch
I am again able to load and use the module.

The commit aef7db4bd5a3b6068dfa05919a3d685199eed116 fixed the problem with
recursive locking in fb blanking code if blank is caused by user setting
the /sys/class/graphics/fb*/blank. However this broke the fbcon timeout
blanking.
If you use a driver that defines ->fb_blank operation and at the same time
that driver relies on other driver (e.g. backlight or lcd class) to blank
the screen, when the fbcon times out and tries to blank the fb, it will
call only fb driver blanker and won't notify the other driver. Thus FB
output is disabled, but the screen isn't blanked.
Restore fbcon blanking and at the same time apply the proper fix for the
above problem: if fbcon_blank is called with FBINFO_FLAG_USEREVENT, we are
already called through notification from fb_blank, thus we don't have to
blank the fb again.

According to the manual the "tdfOnExit" flag must be set on the last byte
we want to send. The PSC controller holds SS low until the flag is set.
However, the flag was set always on the last byte of the FIFO,
independently if it is the last byte of the transfer. This generates
spurious toggling of the SS signals that breaks the protocol of some
peripherals. Fix.

Tecra M4 sometimes forget what it is and reports bogus data via DMI
which makes the machine evade broken suspend matching and thus fail
suspend/resume. This patch updates piix_broken_suspend() such that it
can match such case. As the borked DMI data is a bit generic,
matching many entries to make the match more specific is necessary.
As the usual DMI matching is limited to four entries, this patch uses
hard coded manual matching.
This is reported by Alexandru Romanescu.

When resizing a CQ, MTTs associated with the old CQE buffer were not
freed. As a result, if any app used resize CQ repeatedly, all MTTs
were eventually exhausted, which led to all memory registration
operations failing until the driver is reloaded.
Once the RESIZE_CQ command returns successfully from FW, FW no longer
accesses the old CQ buffer, so it is safe to deallocate the MTT
entries used by the old CQ buffer.
Finally, if the RESIZE_CQ command fails, the MTTs allocated for the
new CQEs buffer also need to be de-allocated.
This fixes <https://bugs.openfabrics.org/show_bug.cgi?id=1416>.

The AT91CAP9 revC CPU has a few differences over the previous,
revB CPU which was distributed in small quantities only (revA was
an internal Atmel product only).
This patch adds the detection routines to recognize the different
AT91CAP9 revisions (based on the PMC subsystem version number), and
uses them to:
- activate a workaround for the external interrupts levels
(on revB CPUs)
- set the UDPHS_BYPASS bit (on revB CPUs)
- set AT91_GPBR register address to the correct offset
(0xfffffd50 on revB, 0xfffffd60 on revC)
For debugging usage, the CPU revision can be found in /proc/cpuinfo
on the 'Revision' line.
This patch is extracted from Andrew Victor's -at91 patch (2.6.27-at91.patch)
where it has been tested for the last 6 months.

This patch (as1176) adds an unusual_devs entry for the Mio C520 GPS
unit. Other devices also based on the Mitac hardware use the same USB
interface firmware, so the Vendor and Product names are generalized.
This fixes Bugzilla #11583.

Gadgets disable endpoints in their disconnect callbacks, so
we must call disconnect before unbinding.
The patch fixes following badness:
root@b1:~# insmod fsl_usb2_udc.ko
Freescale High-Speed USB SOC Device Controller driver (Apr 20, 2007)

Gadgets disable endpoints in their disconnect callbacks, so
we must call disconnect before unbinding. This also fixes
muram memory leak, since we free muram in the qe_ep_disable().
But mainly the patch fixes following badness:
