This reverts commit 556ea928f78a390fe16ae584e6433dff304d3014.
Jeff Chua reports that it can cause some bluetooth devices (he mentions
an Bluetooth Intermec scanner) to just stop responding after a while
with messages like
[ 4533.361959] btusb 8-1:1.0: no reset_resume for driver btusb?
[ 4533.361964] btusb 8-1:1.1: no reset_resume for driver btusb?
from the kernel. See also
https://bugzilla.kernel.org/show_bug.cgi?id=26182
for other reports.

DM9000 revision B needs 1 ms delay after PHY power-on.
PHY must be powered on by writing 0 into register DM9000_GPR before
all other settings will change (see Davicom spec and example code).
Remember, that register DM9000_GPR was not changed by reset sequence.
Without this fix the FIFO is out of sync and sends wrong data after
sequence of "ifconfig ethX down ; ifconfig ethX up".

Correct channel setting function must be used for AR2317.
When I tested ahb patch on bullet2 all seemed to work fine,
but it couldn't connect another host (using ibss for example).
During an analysis I observed that it's transmitting on another
channel. I looked into madwifi code and understood that
the problem is in channel setting function. So atheros RF2317 not
fully handled in the current ath5k version and must be patched.

The DMA latency issue is observed only in Intel pinetrail platforms
but in the driver we had a default PM-QOS value of 55. This caused
unnecessary power consumption and battery drain in other platforms.
Remove the pm-qos thing in the driver code and address the throughput
issue in Intel pinetrail platfroms in user space using any one of
the scripts in below links:

Use of abs() wrongly wrapped diff_ns to 32 bit, which gives a 1/4000
probability of a missed vblank increment at each vblank irq reenable
if the kms driver doesn't support high precision vblank timestamping.

Commit 8ee294cd9def0004887da7f44b80563493b0a097 converted serio
subsystem event handling from using a dedicated thread to using
common workqueue. Unfortunately, this regressed our boot times,
due to the fact that serio jobs take long time to execute. While
the new concurrency managed workqueue code manages long-playing
works just fine and schedules additional workers as needed, such
works wreck havoc among remaining users of flush_scheduled_work().
To solve this problem let's move serio/gameport works from system_wq
to system_long_wq which nobody tries to flush.

This errata occurs when the ARDY interrupt generation is enabled.
At the begining of every new transaction the ARDY interrupt is cleared.
On continuous i2c transactions where after clearing the ARDY bit from
I2C_STAT register (clearing the interrupt), the IRQ line is reasserted and the
I2C_STAT[ARDY] bit set again on 1. In fact, the ARDY status bit is not cleared
at the write access to I2C_STAT[ARDY] and only the IRQ line is deasserted and
then reasserted. This is not captured in the usual errata documents.
The workaround is to have a double clear of ARDY status in irq handler.

When runtime PM is enabled, each OMAP i2c device is suspended after
each i2c xfer. However, there are two cases when the static suspend
methods must be used to ensure the devices are suspended:
1) runtime PM is disabled, either at compile time or dynamically
via /sys/devices/.../power/control.
2) an i2c client driver uses i2c during it's suspend callback, thus
leaving the i2c driver active (NOTE: runtime suspend transitions are
disabled during system suspend, so i2c activity during system
suspend will runtime resume the device, but not runtime (re)suspend it.)
Since the actual work to suspend the device is handled by the
subsytem, call the bus methods to take care of it.
NOTE: This takes care of a known suspend problem on OMAP3 where the
TWL RTC driver does i2c xfers during its suspend path leaving the i2c
driver in an active state (since runtime suspend transistions are
disabled.)

Cancel idle timer in musb_platform_exit.
The idle timer could trigger after clock had been disabled leading to
kernel panic when MUSB_DEVCTL is accessed in musb_do_idle on 2.6.37.
The fault below is no longer triggered on 2.6.38-rc4 (clock is disabled
later, and only if compiled as a module, and the offending memory access
has moved) but the timer should be cancelled nonetheless.

I picked up a new Sierra usb 308 (At&t Shockwave) on 2/2011 and the vendor code
is 0x0f3d
Looking up vendor and product id's I see:
0f3d Airprime, Incorporated
0112 CDMA 1xEVDO PC Card, PC 5220
Sierra and Airprime are somehow related and I'm guessing the At&t usb 308 might
be have some common hardware with the AirPrime SL809x.

tty_port_tty_get may return without any problems NULL. Handle this

If the device isn't reset, the XHCI HCD sends
SET ADDRESS to address 0 while the device is
already in Addressed state, and the request is
dropped on the floor as it is addressed to the
default address. This sequence of events, which this
patch fixes looks like this:
usb_reset_and_verify_device()
hub_port_init()
hub_set_address()
SET_ADDRESS to 0 with 1
usb_get_device_descriptor(udev, 8)
usb_get_device_descriptor(udev, 18)
descriptors_changed() --> goto re_enumerate:
hub_port_logical_disconnect()
kick_khubd()
And then:
hub_events()
hub_port_connect_change()
usb_disconnect()
usb_disable_device()
new device struct
sets device state to Powered
choose_address()
hub_port_init() <-- no reset, but SET ADDRESS to 0 with 1, timeout!
The solution is to always reset the device in
hub_port_init() to put it in a known state.

My Galaxy Spica needs this quirk when in modem mode, otherwise
it causes endless USB bus resets and is unusable in this mode.
Unfortunately Samsung decided to reuse ID of its old CDMA phone SGH-I500
for the modem part.
That's why in addition to this patch the visor driver must be prevented
from binding to SPH-I500 ID, so ACM driver can do that.

[USB]Add Samsung SGH-I500/Android modem ID switch to visor driver
Samsung decided to reuse USB ID of its old CDMA phone SGH-I500 for the
modem part of some of their Android phones. At least Galaxy Spica
is affected.
This modem needs ACM driver and does not work with visor driver which
binds the conflicting ID for SGH-I500.
Because SGH-I500 is pretty an old hardware its best to add switch to
visor
driver in cause somebody still wants to use that phone with Linux.
Note that this is needed only when using the Android phone as modem,
not in USB storage or ADB mode.
