9a4cc5ac99 V4L/DVB (11846): ir-kbd-i2c: Don't assume all IR receivers are supported
The code in ir_probe makes the dangerous assumption that all IR
receivers are supported by the driver. The new i2c model makes it
possible for bridge drivers to instantiate IR devices before they are
supported, therefore the ir-kbd-i2c drivers must be made more robust
to not spam the logs or even crash on unsupported IR devices. Simply,
the driver will not bind to the unsupported devices.

c668f32dca V4L/DVB (11844): ir-kbd-i2c: Switch to the new-style device binding model
Let card drivers probe for IR receiver devices and instantiate them if
found. Ultimately it would be better if we could stop probing
completely, but I suspect this won't be possible for all card types.

There's certainly room for cleanups. For example, some drivers are
sharing I2C adapter IDs, so they also had to share the list of I2C
addresses being probed for an IR receiver. Now that each driver
explicitly says which addresses should be probed, maybe some addresses
can be dropped from some drivers.

Also, the special cases in saa7134-i2c should probably be handled on a
per-board basis. This would be more efficient and less risky than always
probing extra addresses on all boards. I'll give it a try later.

There's existing mutex_lock and mutex_unlock around the actual read but

blocks and this could block another non-blocking reader on the mutex
instead.

1010ed1327 V4L/DVB (11840): change kmalloc to vmalloc for sglist allocation in videobuf_dma_map/unmap
Change kmalloc()/kfree() to vmalloc()/vfree() for sglist allocation
during videobuf_dma_map() and videobuf_dma_unmap()

High resolution sensors might require too many contiguous pages
to be allocated for sglist by kmalloc() during videobuf_dma_map()
(i.e. 256Kib for 8MP sensor).
In such situations, kmalloc() could face some problem to find the
required free memory. vmalloc() is a safer solution instead, as the
allocated memory does not need to be contiguous.

04a37e0f32 V4L/DVB (11837): uvcvideo: Start status polling on device open
Most UVC camera include an interrupt endpoint to report control value changes,
video streaming errors and camera button events. The USB controller
continuously polls the interrupt endpoint to retrieve such events. This
prevents the device from being auto-suspended, and thus consumes power.

Reporting video streaming errors don't make sense when the V4L2 device is
closed. Control value changes are probably useless as well if nobody listens to
the events, although caching will probably have to be completely disabled then.
No polling is thus be required when /dev/videoX is not opened.

To enable auto-suspend and save power do not poll the interrupt endpoint until
the device is open. We lose the ability to detect button events if no
application is using the camera.

d18e2fda71 V4L/DVB (11810): em28xx: properly set packet size based on the device's eeprom configuration.
The em28xx actually has a register that tells the driver what the maximum
packet size is (based on a value programmed into the eeprom).  Make use of
that register instead of assuming a hardcoded value of 564 (since 564 is not
correct for devices that do QAM such as the KWorld 340u).

Note that for now the em2874 code isn't there, falling back to the 564 value,
however this is not a problem since there are not any em2874 based devices in
the current v4l-dvb tree).

Thanks to Jarod Wilson for detecting the initial problem and figuring out that
the isoc configuration was wrong for his device.

b8d91986e6 V4L/DVB (11807): cx88: remove xc5000 reset for Pinnacle 800i
According to the engineer at PCTV Systems, the xc5000 reset pin is supposed
to be on GPIO12.  However, despite three nights of effort, pulling that GPIO
low didn't reset the xc5000.  While pulling MO_SRST_IO low does reset the
xc5000, this also resets in the s5h1409 being reset as well.  This causes
tuning to always fail since the internal state of the s5h1409 does not match
the driver's state.

Given that the only two conditions in which the driver performs a reset is
during firmware load and powering down the chip, I am taking out the reset.
We know that the chip is being reset when the cx88 comes online, and not being
able to do power management for this board is better than not having any
tuning at all.

Problem discovered when implementing proper power management for the xc5000,
which results in calls to the reset callback *after* s5h1409 is initialized.

properly implement i2c clock stretching (since the five register writes that
occur for a tuning request often do not complete immediately but do complete
far before 100ms has gone by).

The net amount of time we wait before timing out is unchanged (500ms).

81c4dfe776 V4L/DVB (11796): xc5000: start using the newer "finerfreq" tuning command
Starting in firmware version 1.1.44, Xceive recommends using the FINERFREQ for
all normal tuning (the doc indicates reg 0x03 should only be used for fast
scanning for channel lock)

b25ed9c535 V4L/DVB (11794): au0828: reduce reset time for xc5000 to 10ms
The xc5000 datasheet indicates that the reset pin only needs to be held low
for 10ms.  Reduce the value accordingly, which speeds up the firmware load
time a bit.

7f05b530be V4L/DVB (11793): xc5000: Properly support power down for newer firmware
Xceive got rid of the XREG_POWER_DOWN register in later firmware revisions.
Their technical support informed me that the correct way to put the tuner
to sleep is to pull the reset pin (but don't reload the firmware).

361d4892cd V4L/DVB (11792): xc5000: switch to new version of Xceive firmware
This switches to a new version of the xc5000 firmware, extracted from the
latest Hauppauge driver.  It includes the support for the XREG_BUSY register
(a lack of which was causing tuning to take 3200ms instead of around 300ms).

a78baacffe V4L/DVB (11791): xc5000: do not sleep after digital tuning
Don't sleep for 400ms polling the tuner's lock if in digital mode (since the
xc5000 lock status registers appear to only be reliable in analog mode)

8e4c67972e V4L/DVB (11790): xc5000: restore sleep routine
Bring back the code that puts the xc5000 to sleep.  For the Pinnacle 801e
this results in power consumption at idle dropping from 325ma to 124ma.

If there are *actually* any devices that don't work in this configuration,
they should set dvb_frontend.ops.tuner_ops.sleep to NULL (per mkrufky's
suggestion)

Also, had to make sure we were making sure the firmware was loaded in the
digital version of set_params, or else we end up get i2c errors if the
device is asleep
