7641b04421 media: i2c: Copy mt9t112 soc_camera sensor driver
Copy the soc_camera based driver in v4l2 sensor driver directory.
This commit just copies the original file without modifying it.
No modification to KConfig and Makefile as soc_camera framework
dependencies need to be removed first in next commit.

7772e380ef media: af9015: enhance streaming config
Replace static stream settings by one which enables and disables
stream interface when needed (TS streaming control).

1) Configure both TS IF and USB endpoints according to current use case

2) Disable streaming USB endpoints when streaming is stopped and
enable when streaming is started. Reduces sleep power consumption
slightly.

3) Reduce USB buffersize slightly, from 130848 to 98136 bytes

279c60fd89 media: mceusb: add IR learning support features (IR carrier frequency measurement and wide-band/short-range receiver)
Windows Media Center IR transceivers include two IR receivers;
wide-band/short-range and narrow-band/long-range. The short-range
(5cm distance) receiver is for IR learning and has IR carrier

and enable pass through of its IR carrier frequency measurements.

RC and LIRC already support these mceusb driver additions.

b358e747ae media: rc: meson-ir: lower timeout and make configurable
A timeout of 200ms is much longer than necessary, and delays the decoding
decoding of a single scancode and the last scancode when a button is being

If the min_timeout and max_timeout values are set, the timeout is
configurable via the LIRC_SET_REC_TIMEOUT ioctl.

71569850e3 media: i2c: adv748x: Add missing CBUS page
The ADV748x has 12 pages mapped onto I2C addresses.

In the existing implementation only 11 are mapped correctly in the page
enumerations, which causes an off-by-one fault on pages above the
infoframe definition due to a missing 'CBUS' page.

This causes the address for the CEC, SDP, TXA, and TXB to be incorrectly
programmed during the iterations in adv748x_initialise_clients().

Until now this has gone un-noticed due to the fact that following the
creation of the clients - the device is reset and the addresses are
reprogrammed in manually by the call to "adv748x_write_regs(state,
adv748x_set_slave_address);"

As part of moving to dynamic i2c address allocations repair this by
providing the missing CBUS page definition.

3aab15af9a media: add tuner standby op, use where needed
The v4l2_subdev core s_power op was used for two different things: power on/off
sensors or video decoders/encoders and to put a tuner in standby (and only the
tuner!). There is no 'tuner wakeup' op, that's done automatically when the tuner
is accessed.

The danger with calling (s_power, 0) to put a tuner into standby is that it is
usually broadcast for all subdevs. So a video receiver subdev that supports
s_power will also be powered off, and since there is no corresponding (s_power, 1)
they will never be powered on again.

In addition, this is specifically meant for tuners only since they draw the most
current.

This patch adds a new tuner op called 'standby' and replaces all calls to
(core, s_power, 0) by (tuner, standby). This prevents confusion between the two
uses of s_power. Note that there is no overlap: bridge drivers either just want
to put the tuner into standby, or they deal with powering on/off sensors. Never
both.

This also makes it easier to replace s_power for the remaining bridge drivers
with some PM code later.

Whether we want something cleaner for tuners in the future is a separate topic.
There is a lot of legacy code surrounding tuners, and I am very hesitant about
making changes there.

95ce9c2860 media: v4l: common: Add a function to obtain best size from a list
Add a function (as well as a helper macro) to obtain the best size in a
list of device specific sizes. This helps writing drivers as well as
aligns interface behaviour across drivers.

The struct in which this information is contained in is typically specific
to the driver, therefore the existing function v4l2_find_nearest_format()
does not address the need.

2525fdcb6e media: imon: rename protocol from other to imon
This renames the protocol for the imon rc driver from other to imon,
since it is now an known protocol. Although different name will show up
in the sysfs protocol file, loading a keymap using existing ir-keytable
versions still works.

8d4068810d media: rc: oops in ir_timer_keyup after device unplug
If there is IR in the raw kfifo when ir_raw_event_unregister() is called,
then kthread_stop() causes ir_raw_event_thread to be scheduled, decode
some scancodes and re-arm timer_keyup. The timer_keyup then fires when
the rc device is long gone.
