On certain configurations, HPA isn't or can't be unlocked during
probing but it somehow ends up unlocked afterwards. In the following
thread, the problem can be reliably reproduced after resuming from
STR. The BIOS turns on HPA during boot but forgets to do it during
resume.
http://thread.gmane.org/gmane.linux.kernel/858310
This patch updates libata revalidation such that it considers native
n_sectors. If the device size has increased to match native
n_sectors, it's assumed that HPA has been unlocked involuntarily and
the device is recognized as the same one. This should be fairly safe
while nicely working around the problem.

Please consider the following updates and fixes for pata_at91 driver.
* Removed extra headers
Here we need only static memory controller properties, which are
contained in generic header at91sam9_smc.h.
No need to include any specific headers for at91sam9260 SoC.
* No harsh BUG_ON for get_clk in set_smc_timing function
get_clk is now performed in driver probing function,
probing fails if master clock is not available

Correct the xHCI code to handle stalls on USB endpoints. We need to move
the endpoint ring's dequeue pointer past the stalled transfer, or the HW
will try to restart the transfer the next time the doorbell is rung.
Don't attempt to clear a halt on an endpoint if we haven't seen a stalled
transfer for it. The USB core will attempt to clear a halt on all
endpoints when it selects a new configuration.

The xHCI host controller can be programmed to retry a transfer a certain number
of times per endpoint before it passes back an error condition to the host
controller driver. The xHC will return an error code when the error count
transitions from 1 to 0. Programming an error count of 3 means the xHC tries
the transfer 3 times, programming it with a 1 means it tries to transfer once,
and programming it with 0 means the HW tries the transfer infinitely.
We want isochronous transfers to only be tried once, so set the error count to
one.

When there is a short packet on a control transfer, the xHCI host controller
hardware will generate two events. The first event will be for the data stage
TD with a completion code for a short packet. The second event will be for the
status stage with a successful completion code. Before this patch, the xHCI
driver would giveback the short control URB when it received the event for the
data stage TD. Then it would become confused when it saw a status stage event
for the endpoint for an URB it had already finished processing.
Change the xHCI host controller driver to wait for the status stage event when
it receives a short transfer completion code for a data stage TD.

There are several xHCI data structures that use two 32-bit fields to
represent a 64-bit address. Since some architectures don't support 64-bit
PCI writes, the fields need to be written in two 32-bit writes. The xHCI
specification says that if a platform is incapable of generating 64-bit
writes, software must write the low 32-bits first, then the high 32-bits.
Hardware that supports 64-bit addressing will wait for the high 32-bit
write before reading the revised value, and hardware that only supports
32-bit writes will ignore the high 32-bit write.
Previous xHCI code represented 64-bit addresses with two u32 values. This
lead to buggy code that would write the 32-bits in the wrong order, or
forget to write the upper 32-bits. Change the two u32s to one u64 and
create a function call to write all 64-bit addresses in the proper order.
This new function could be modified in the future if all platforms support
64-bit writes.

When an endpoint on a device under an xHCI host controller stalls, the
host controller driver must let the hardware know that the USB core has
successfully cleared the halt condition. The HCD submits a Reset Endpoint
Command, which will clear the toggle bit for USB 2.0 devices, and set the
sequence number to zero for USB 3.0 devices.
The xHCI urb_enqueue will accept new URBs while the endpoint is halted,
and will queue them to the hardware rings. However, the endpoint doorbell
will not be rung until the Reset Endpoint Command completes.
Don't queue a reset endpoint command for root hubs. khubd clears halt
conditions on the roothub during the initialization process, but the roothub
isn't a real device, so the xHCI host controller doesn't need to know about the
cleared halt.

I've opened up the case, and the chips in the ATEN UC2324 are:
Moschip
MCS7840CV-AA
69507-6B1
0650
(USB to 4-port serial)
(logo with AF kerned together) 0748
24BC02
SINGLP
(unknown 8-pin chip)
(logo looks like 3 or Z in circle)
ZT3243LEEA 0752
B7A16420.T
(4 chips, so this will be RS232 line driver)
(Probably equivalent of Sipex SP3243)
So the ATEN 2324 (aten2011.c driver), is definitely the Moschip 7840,
and should use the mos7840.c driver. I expect you will remove the
aten2011.c driver from the staging area.
From the aten2011.c source code, the device ID for the UC2322 (2 port
serial) is 0x7820, just like the Moschip evaluation board. This value
should be added to the device id table of mos7840.c.

When a net device goes down or when the bnx2i driver is unloaded,
the code was not generating the ISCSI_KEVENT_IF_DOWN message
properly and this could cause the userspace driver to crash.
This is fixed by sending the message properly in the shutdown path.
cnic_uio_stop() is also added to send the message when bnx2i is
unregistering.

There is an 82599 errata that UDP frames with a zero checksum are

Some 8168 are unable to WoL when receiving is not enabled (plain
old 8169 do not seem to care).
It is not exactly pretty to leave the receiver enabled but we
should now enable DMA late enough for it to be safe. Some late
stage boot failure due to pxe and friends may benefit from the
delayed enabling of bus-mastering as well.

Both tvaudio and the tuner share i2c address 0x42. The tvaudio module can
check whether it really is a tda9840, but the tuner can't. So the tvaudio
module must be loaded before the tuner module. This was also the case for
2.6.29, but the order was swapped in 2.6.30.

A recent patch didn't take into account that frontends can be compiled into
the kernel. Or that frontends compiled as modules can't be used by the
b2c2 driver if it is not a module itself.
Some frontends require multiple drivers, e.g. a demod driver and a tuner
driver. The code for the frontend support was getting added if the demod
driver was available. Change this to also require any needed tuner or SEC
drivers as well.

When the change was introduced in the zl10353 for the i2c gate behavior, this
broke the HVR-900 which was not behind a gate. Use a version of the zl10353
config profile that indicates the tuner is not behind such a gate.
Without this patch the first tune succeeds, but subsequent tuning attempts
will fail.
The change also renames the terratec zl10353 profile I wrote to be more
generic, since it is shared by the non-terratec device.
Thanks to Michael Krufky for providing a HVR-900 and DVB-T environment to test
with.

In cases where the device has a generic Empia USB ID, the call in the
precard setup phase did not set the tuner GPIO. As a result, the tuner may
not be taken out of reset before attempting initialization in the analog
driver.
This problem was not seen before with the EVGA inDtube, since that particular
board has the analog GPIO setup to include taking the tuner out of reset.

Depending on the video input format, vinmode/vinctl needs adjustments.
For TV, this is not relevant, since the supported decoders output data
at the same format. However, webcam sensors may have different formats,
so, this needs to be adjusted based on the device.

In order to properly estimate fps, mt9v011 sensor driver needs to know
what is the used frequency on the sensor cristal. Adds the proper fields
and initialization code for specifying the cristal frequency.
Also, based on experimentation, it was noticed that the Silvercrest is
outputing data at 7 fps. This means that it should be using a 6.3 MHz
cristal. This information needs to be double checked later, by opening
the device. Anyway, by using this value for xtal, at least now we have
the correct fps report.

It is possible to adjust the fps rate by changing some register values.
This is function of the connected Xtal at the camera sensor, being a 27
MHz cristal needed, in order to support 640x480 at 30 fps.
For now, it will only calculate the values for fps. Later patches may
introduce V4L2 ioctls, to allow frequency rate adjustments.

While trying to fix an mt9v001 webcam, I noticed that HSCALE/VSCALE do
work with em28xx + webcam. The issue is that the scaling setup depends
on the number of visible rows/cols of the input image.
With mt9v011 (Silvercrest), the resolution is 640x480. So, the scaling
is different from a normal TV image (720x480 on NTSC). This were causing
a wrong scaling and a previous patch disabled scaling.
As each sensor have their different resolution setting, the xres/yres
should be adjusted accordingly with the input sensor.

With the previous approach, autodetection were working only for the two
generic entries (em275x and em2820 unknown ones). So, if someone would
try to force probing an specific device, the code would not properly run
the autodetection code.
With the new approach, the sensor autodetection will be run not only for
the two generic entries, but also do webcam specific ones.

Instead of using em28xx board decoder field for storing sensor information,
let's use instead a separate field for it.
Also, as sensors are currently autodetected, there's no need of having
it at the boards description. So, move it to the main em28xx struct.
