USB: aten uc2324 is really a moschip 7840
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.
Here's a patch that adds these devices to the driver.

Requests to get max LUN, for certain USB storage devices, require a
longer timeout before a correct reply is returned. This happens for a
Realtek USB Card Reader (0bda:0152), which has a max LUN of 3 but is set
to 0, thus losing functionality, because of the timeout occurring too
quickly.
Raising the timeout value fixes the issue and might help other devices

mm: Pass virtual address to [__]p{te,ud,md}_free_tlb()
Upcoming paches to support the new 64-bit "BookE" powerpc architecture
will need to have the virtual address corresponding to PTE page when
freeing it, due to the way the HW table walker works.
Basically, the TLB can be loaded with "large" pages that cover the whole
virtual space (well, sort-of, half of it actually) represented by a PTE
page, and which contain an "indirect" bit indicating that this TLB entry
RPN points to an array of PTEs from which the TLB can then create direct
entries. Thus, in order to invalidate those when PTE pages are deleted,
we need the virtual address to pass to tlbilx or tlbivax instructions.
The old trick of sticking it somewhere in the PTE page struct page sucks
too much, the address is almost readily available in all call sites and
almost everybody implemets these as macros, so we may as well add the
argument everywhere. I added it to the pmd and pud variants for consistency.

V4L/DVB (12265): em28xx: fix tuning problem in HVR-900 (R1)
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.
V4L/DVB (12263): em28xx: set demod profile for Pinnacle Hybrid Pro 320e
The Pinnacle Hybrid Pro 320e was missing a demod config for the xc3028, which
is required for digital tuning to work properly. Add the missing profile.
Thanks to Andreas Lunderhage for testing patches and providing a remote debug
environment.
V4L/DVB (12262): em28xx: Make sure the tuner is initialized if generic empia USB id was used
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.
Thanks to Andreas Lunderhage for testing patches and providing a remote debug
environment for the Pinnacle 320e.
V4L/DVB (12258): em28xx: fix typo in mt352 init sequence for Terratec Cinergy T XS USB
Andy walls pointed out that we were passing 0x5d to the TUNER_GO register,
instead of 0x01. Set the register properly (note the code did still work with
the incorrect value, so this does not address a regression).
V4L/DVB (12244): em28xx: adjust vinmode/vinctl based on the stream input format
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.
V4L/DVB (12243): em28xx: allow specifying sensor xtal frequency
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.
V4L/DVB (12242): mt9v011: implement core->s_config to allow adjusting xtal frequency
Since frames per second is a function of cristal frequency, and this is
device-specific, add a function that allows adjusting it, via
subdev->core->s_config callback.
V4L/DVB (12240): mt9v011: add a function to calculate frames per second rate
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.
V4L/DVB (12238): em28xx: call sensor detection code for all webcam entries
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.
All hdcs registers use bit 0 as a read/write flag and needs to be shifted one bit to the left. This wasn't accounted for when doing a sequence of writes.

[S390] zcrypt: fix scheduling of hrtimer ap_poll_timer
Every time a request is enqueued or there is some work outstanding
from the ap_tasklet, the ap_poll_timer is scheduled again.
Unfortunately it was permanently called. It looked as if it was
started in the past and thus imediately expired.
This has been changed. First it is checked if the hrtimer is already
expired. Then the expiring time is forwarded and the timer restarted.
