5afc9a25be [media] Add support for TechniSat Skystar S2
This patch adds support for the Technisat Skystar S2 - this
has been tried before but the cx24120 driver was a bit out of shape
and it didn't got any further:

https://patchwork.linuxtv.org/patch/10575/

It is an old card, but currently being sold off for next to nothing,
so it's proving quite popular of late. Noticing it's quite similar
to the cx24116 and cx24117 I've rewritten the driver in a similar way.

There were a few registers and commands from those drivers
missing from this one I've tested out and found they do something so
they've been added in to speed up tuning and to make get_frontend
return something useful.

0fae1997f0 [media] dib0700: avoid the risk of forgetting to add the adapter's size
For every frontend entry, we need to add the adapter's size. There
are already two patches fixing it. So, it doesn't seem trivial to
keep it there at the right place.

Also, currently, the indentation is wrong on all places.

So, it seems that keeping it right is not too trivial.

Better to use a macro that would do it for us, at least while
this is not converted to dvb-usb-v2.

0d830b2d12 [media] rc: rc-core: Add support for encode_wakeup drivers
Add support in rc-core for drivers which implement the wakeup scancode
filter by encoding the scancode using the raw IR encoders. This is by
way of rc_dev::encode_wakeup which should be set to true to make the
allowed wakeup protocols the same as the set of raw IR encoders.

As well as updating the sysfs interface to know which wakeup protocols
are allowed for encode_wakeup drivers, also ensure that the IR
decoders/encoders are loaded when an encode_wakeup driver is registered.

The protocol is chosen based on the specified protocol mask, and
whether all the required bits are set in the scancode mask, and none of

The Manchester modulation helper is used several times with various
timings so that RC-6 header preamble, the header, header trailing bit
and the data itself can be modulated correctly.

a0466f15b4 [media] rc: ir-rc5-decoder: Add encode capability
Add the capability to encode RC-5, RC-5X and RC-5-SZ scancodes as raw
events. The protocol is chosen based on the specified protocol mask,
and whether all the required bits are set in the scancode mask, and
none of the unused bits are set in the scancode data. For example a
scancode filter with bit 16 set in both data and mask is unambiguously
RC-5X.

The Manchester modulation helper is used, and for RC-5X it is used twice
with two sets of timings, the first with a short trailer space for the
space in the middle, and the second with no leader so that it can
continue the space.

The encoding in RC-5-SZ first inserts a pulse and then simply utilizes
the generic Manchester encoder available in rc-core.

My static checker warns that the name of the port can be 15 characters

It's unlikely that we hit the limit and even if we do the overflow will

Converting debug prints to use pr_foo() is not trivial, as the

pieces of the code that prints the I2C transfers. Those use a
lot pr_cont(), and, depending on using either level 1 or 2,
a different set of macros are selected.

c6c62cce32 [media] saa7134: better handle core debug messages
On media drivers, debugging messages should be grouped into
categories, as this makes easier to debug the driver.

In the case of saa7134, the core has 2 debug categories, one
for IRQ, and another one for the core itself. The IRQ have
actually 2 levels of debug.

So, instead of using pr_dbg(), where everything would be in
the same box, let's define two macros that use pr_fmt(),
one for the core, and another one for irq.

With that, we can replace the remaining printk() occurrences
at the core to use either core_dbg() or irq_dbg(), depending
on the group of debug macros that need to be enabled.

699dcffc52 [media] rtl2832: add support for GoTView MasterHD 3 USB tuner
GoTView MasterHD 3 is a DVB-T2/C USB 2.0 tuner.

It's based on the following components:
- USB bridge: RTL2832P (contains also DVB-T demodulator)
- Demodulator: Si2168-A30
- Tuner: Si2148-A20

The demodulator and the tuner will need firmwares. The Si2148 uses Si2158
firmware. Antti has the firmwares available for download:
http://palosaari.fi/linux/v4l-dvb/firmware/

Do note that for DVB-T either of the demodulators can be used. DVB-C and
DVB-T2 are only supported by the Si2168 demodulator. The driver will
register 2 frontends for the same adapter. Frontend 0 will be the RTL2832
demodulator and frontend 1 will be the Si2168 demodulator. The same
tuner is used for both.

As a consequence of the above, it's recommended to use application that
does implement proper DVBv5 support.

For some reason, the old I2C write method sporadically fails. Thus the
need for an option to only use the new I2C write method supported by the
RTL2832.

c3f22501b5 media controller: add EXPERIMENTAL to Kconfig option for DVB support
The Media Controller DVB support is still an experimental feature,
as it is under heavy development. It is already said that it is
an experimental feature at the help, but let make it even clearer
and louder, as we may need to adjust some bits when we start using it
on embedded drivers.

1e4cbe677f [media] marvell-ccic: control handler fixes
No controls were reported, even though the ov7670 does have controls.

Two reasons for this: the v4l2_ctrl_handler_init() call must come
before the ov7670 is loaded (otherwise the ov7670 won't know that
its controls should be added to the bridge driver), and the
v4l2_ctrl_handler_free() call at the end should only be called if
the ret value is non-zero (otherwise you would just free all the
controls that were just added).

48b25a3a71 [media] vb2: Push mmap_sem down to memops
Currently vb2 core acquires mmap_sem just around call to
__qbuf_userptr(). However since commit f035eb4e97 (videobuf2: fix
lockdep warning) it isn't necessary to acquire it so early as we no
longer have to drop queue mutex before acquiring mmap_sem. So push
acquisition of mmap_sem down into .get_userptr and .put_userptr memops
so that the semaphore is acquired for a shorter time and it is clearer
what it is needed for.

f67476589a [media] v4l2-dv-timings: fix rounding error in vsync_bp calculation
Changed the rounding offsets used in vsync_bp calculation in cvt and
gtf timings. The results for vsync_bp should now match with results
from timing generator spreadsheets for cvt and gtf standards.

In the vsync_bp calculation for cvt, always round down the value of
(CVT_MIN_VSYNC_BP / h_period_est) and then add 1. It thus, reflects
the equation used in timing generator spreadsheet. Using 1999999 as
rounding offset, could pontentially lead to bumping up the vsync_bp
value by extra 1.

In the vsync_bp calculations for gtf, instead of round up or round
down, round the (CVT_MIN_VSYNC_BP / h_period_est) to the nearest
integer.

Thanks to Martin Bugge <marbugge@cisco.com> for validating with
standards and suggestions on equations.

already have an explicit dependency on HAS_DMA.

Make VIDEOBUF2_DMA_SG depend on HAS_DMA. This makes it easier to find

	drivers/media/pci/bt8xx/bttv-audio-hook.c:371 adtvk503_audio() warn: bitwise AND condition is false here

there are some serious issues at the audio hook implementation.

They're not following what's specified at the DocBook:
	http://linuxtv.org/downloads/v4l-dvb-apis/vidioc-g-tuner.html#tuner-audmode

Basically, it was assuming that the audmode (V4L2_TUNER_MODE_foo)
is a variable with a bit maskk. However, it isn't.

The bitmask only applies to rxsubchans field (V4L2_TUNER_SUB_foo).

As the code is also too complex, and not all hooks were returning
both audmode and rxsubchans to a VIDIOC_G_TUNER, rewrite the
functions, in order to fix both for get and set tuner ioctls.

f3f8ef2274 [media] dib0070: Fix indenting
The indentation on this driver were deadly broken. On lots
of places, it was using 4 spaces instead of tab to indent.
On other parts, it were using tabs.

Also, on several places, it were not even being properly aligned,
as reported by smatch:
	drivers/media/dvb-frontends/dib0070.c:179 dib0070_set_bandwidth() warn: inconsistent indenting

	drivers/media/dvb-frontends/dib0070.c:713 dib0070_reset() warn: inconsistent indenting

My first idea were to leave it as-is or to just touch the above.

However, this won't be fixing anything. So, as painful as it
is, let's fix indentation globally on the driver, and then
address the inconsistencies.

Hopefully, this driver doesn't have much patches, so it likely
won't conflict to any other patch during this merge window.

Besides the big size of this patch, no functional changes
were done.

d487df9ef9 [media] ov7670: check read error also for REG_AECHH on ov7670_s_exp()
ov7670_s_exp() checks read error for 2 registers: REG_COM1
and REG_COM8. But, although it uses the value latter, it
doesn't check errors on REG_AECHH read. Yet, as it is doing
a bitmask operation there, the read operation should succeed.

So, fix the code to also check if this succeeded.

This fixes this smatch report:

As reported by smatch:
	drivers/media/usb/gspca/zc3xx.c:5994 transfer_update() info: ignoring unreachable code.

That happens because there's a return that it is never called,
as the work queue runs an infinite loop, except when the device is
put to sleep or an error happens.

When an error happens, a break statement is enough to go out of
the loop. So, let's remove the goto, as break is the typical
instruction used to end a loop.

As reported by smatch:

	drivers/media/i2c/saa717x.c:155 saa717x_read() warn: mask and shift to zero

This is done right at saa717x_write(), but the read function is
broken. Thankfully, there's just one place at saa717x driver that
uses multibyte read (for status report, via printk).

Yet, let's fix it. From saa717x_write(), it is clear that the
bytes are in little endian:
		mm1[4] = (value >> 16) & 0xff;
		mm1[3] = (value >> 8) & 0xff;
		mm1[2] = value & 0xff;

So, the same order should be valid for read too.

Compile-tested only.

698da18e08 [media] v4l: of: Parse variable length properties --- link-frequencies
The link-frequencies property is a variable length array of link frequencies
in an endpoint. The array is needed by an increasing number of drivers, so
it makes sense to add it to struct v4l2_of_endpoint.

However, the length of the array is variable and the size of struct
v4l2_of_endpoint is fixed since it is allocated by the caller. The options
here are

1. to define a fixed maximum limit of link frequencies that has to be the
global maximum of all boards. This is seen as problematic since the maximum
could be largish, and everyone hitting the problem would need to submit a
patch to fix it, or

2. parse the property in every driver. This doesn't sound appealing as two
of the three implementations submitted to linux-media were wrong, and one of
them was even merged before this was noticed, or

3. change the interface so that allocating and releasing memory according to
the size of the array is possible. This is what the patch does.

v4l2_of_alloc_parse_endpoint() is just like v4l2_of_parse_endpoint(), but it
will allocate the memory resources needed to store struct v4l2_of_endpoint
and the additional arrays pointed to by this struct. A corresponding release
function v4l2_of_free_endpoint() is provided to release the memory allocated
by v4l2_of_alloc_parse_endpoint().

In addition to this, the link-frequencies property is parsed as well, and
the result is stored to struct v4l2_of_endpoint field link_frequencies.

2a700d8edf [media] marvell-ccic: fix Y'CbCr ordering
Various formats had their byte ordering implemented incorrectly, and
the V4L2_PIX_FMT_UYVY is actually impossible to create, instead you
get V4L2_PIX_FMT_YVYU.

This was working before commit ad6ac45222
("add new formats support for marvell-ccic driver"). That commit broke
the original format support and the OLPC XO-1 laptop showed wrong
colors ever since (if you are crazy enough to attempt to run the latest
kernel on it, like I did).

The email addresses of the authors of that patch are no longer valid,
so without a way to reach them and ask them about their test setup
I am going with what I can test on the OLPC laptop.

If this breaks something for someone on their non-OLPC setup, then
contact the linux-media mailinglist. My suspicion however is that
that commit went in untested.

1d11437f4f media: remove unused variable that causes a warning
My 'allmodconfig' build is _almost_ free of warnings, and most of the
remaining ones are for legacy drivers that just do bad things that I
can't find it in my black heart to care too much about.  But this one
was just annoying me:

   drivers/media/v4l2-core/videobuf2-core.c:3256:26: warning: unused variable ‘fileio’ [-Wunused-variable]

because commit 0e66100637 ("[media] vb2: fix 'UNBALANCED' warnings
when calling vb2_thread_stop()") removed all users of 'fileio' and
instead calls "__vb2_cleanup_fileio(q)" to clean up q->fileio.  But the
now unused 'fileio' variable was left around.

d8fbe341be dma-buf: cleanup dma_buf_export() to make it easily extensible
At present, dma_buf_export() takes a series of parameters, which
makes it difficult to add any new parameters for exporters, if required.

Make it simpler by moving all these parameters into a struct, and pass
the struct * as parameter to dma_buf_export().

While at it, unite dma_buf_export_named() with dma_buf_export(), and
change all callers accordingly.

12) Split out new connection request sockets so that they can be

    hash lookups go direct to the request sockets instead of having to
    go first to the listener then to the request socks hashed
    underneath.  From Eric Dumazet.

13) Add async I/O support for crytpo AF_ALG sockets, from Tadeusz Struk.

14) Support stable privacy address generation for RFC7217 in IPV6.  From

Pull power management and ACPI updates from Rafael Wysocki:
 "These are mostly fixes and cleanups all over, although there are a few
  items that sort of fall into the new feature category.

  First off, we have new callbacks for PM domains that should help us to
  handle some issues related to device initialization in a better way.

  There also is some consolidation in the unified device properties API
  area allowing us to use that inferface for accessing data coming from
  platform initialization code in addition to firmware-provided data.

  We have some new device/CPU IDs in a few drivers, support for new
  chips and a new cpufreq driver too.

  Specifics:

   - Generic PM domains support update including new PM domain callbacks
     to handle device initialization better (Russell King, Rafael J
     Wysocki, Kevin Hilman)

   - Unified device properties API update including a new mechanism for
     accessing data provided by platform initialization code (Rafael J
     Wysocki, Adrian Hunter)

   - ARM cpuidle update including ARM32/ARM64 handling consolidation
     (Daniel Lezcano)

   - intel_idle update including support for the Silvermont Core in the
     Baytrail SOC and for the Airmont Core in the Cherrytrail and
     Braswell SOCs (Len Brown, Mathias Krause)

   - New cpufreq driver for Hisilicon ACPU (Leo Yan)

   - intel_pstate update including support for the Knights Landing chip
     (Dasaratharaman Chandramouli, Kristen Carlson Accardi)

   - QorIQ cpufreq driver update (Tang Yuantian, Arnd Bergmann)

   - powernv cpufreq driver update (Shilpasri G Bhat)

   - devfreq update including Tegra support changes (Tomeu Vizoso,
     MyungJoo Ham, Chanwoo Choi)

   - powercap RAPL (Running-Average Power Limit) driver update including
     support for Intel Broadwell server chips (Jacob Pan, Mathias Krause)

   - ACPI device enumeration update related to the handling of the
     special PRP0001 device ID allowing DT-style 'compatible' property
     to be used for ACPI device identification (Rafael J Wysocki)

   - ACPI EC driver update including limited _DEP support (Lan Tianyu,
     Lv Zheng)

   - ACPI backlight driver update including a new mechanism to allow
     native backlight handling to be forced on non-Windows 8 systems and
     a new quirk for Lenovo Ideapad Z570 (Aaron Lu, Hans de Goede)

   - New Windows Vista compatibility quirk for Sony VGN-SR19XN (Chen Yu)

   - Assorted ACPI fixes and cleanups (Aaron Lu, Martin Kepplinger,
     Masanari Iida, Mika Westerberg, Nan Li, Rafael J Wysocki)

   - Fixes related to suspend-to-idle for the iTCO watchdog driver and
     the ACPI core system suspend/resume code (Rafael J Wysocki, Chen Yu)

   - PM tracing support for the suspend phase of system suspend/resume
     transitions (Zhonghui Fu)

   - Configurable delay for the system suspend/resume testing facility
     (Brian Norris)

   - PNP subsystem cleanups (Peter Huewe, Rafael J Wysocki)"

e183201b9e [media] uvcvideo: add support for VIDIOC_QUERY_EXT_CTRL
Add support for the new VIDIOC_QUERY_EXT_CTRL ioctl. Since uvc doesn't use
the control framework, support for this ioctl isn't automatic.

This is makes v4l2-compliance happy as well.

1461fe7ab6 [media] uvcvideo: fix cropcap v4l2-compliance failure
The v4l2-compliance tool expects that if VIDIOC_CROPCAP is defined, then
VIDIOC_G_SELECTION for TGT_CROP_BOUNDS/DEFAULT is also defined (or COMPOSE
in the case of an output device).

In fact, all that a driver has to do to implement cropcap is to support
those two targets since the v4l2 core will implement cropcap and fill in
the pixelaspect to 1/1 by default.

Implementing cropcap is only needed if the pixelaspect isn't square.

So implement g_selection instead of cropcap in uvc to fix the v4l2-compliance
failure.
