0185f85017 [media] samples: v4l: from Documentation to samples directory
With the new autoksyms support, we can run into a situation where
the v4l pci skeleton module is the only one using some exported
symbols that get dropped because they are never referenced by
the kernel otherwise, causing a build problem:

ERROR: "vb2_dma_contig_memops" [Documentation/video4linux/v4l2-pci-skeleton.ko] undefined!
ERROR: "vb2_dma_contig_init_ctx_attrs" [Documentation/video4linux/v4l2-pci-skeleton.ko] undefined!

ERROR: "vb2_dma_contig_cleanup_ctx" [Documentation/video4linux/v4l2-pci-skeleton.ko] undefined!

Specifically, we do look in the samples directory for users of
symbols, but not the Documentation directory.

This solves the build problem by moving the connector sample into
the same directory as the other samples.

11a2a949d0 [media] em28xx: add support for Hauppauge WinTV-dualHD DVB tuner
Hauppauge WinTV-dualHD is a USB 2.0 dual DVB-T/T2/C tuner with
following components:

USB bridge: Empia EM28274 (chip id is the same as EM28174)
Demodulator: 2x Silicon Labs Si2168-B40
Tuner: 2x Silicon Labs Si2157-A30

This patch adds support only for the first tuner.

The demodulator needs firmware, available for example here:
http://palosaari.fi/linux/v4l-dvb/firmware/Si2168/Si2168-B40/4.0.11/

The demodulators sit on the same I2C bus and their addresses
are 0x64 and 0x67. The tuners are behind the demodulators and
their addresses are 0x60 and 0x63.

934275c480 samples: v4l: from Documentation to samples directory
A small bug with the new autoksyms support showed that there are
two kernel modules in the Documentation directory that qualify
as samples, while all other samples are in the samples/ directory.

This patch was originally meant as a workaround for that bug, but
it has now been solved in a different way. However, I still think
it makes sense as a cleanup to consolidate all sample code in
one place.

ab22e77cd3 [media] media framework: rename pads init function to media_entity_pads_init()
With the MC next gen rework, what's left for media_entity_init()
is to just initialize the PADs. However, certain devices, like
a FLASH led/light doesn't have any input or output PAD.

So, there's no reason why calling media_entity_init() would be
mandatory. Also, despite its name, what this function actually
does is to initialize the PADs data. So, rename it to
media_entity_pads_init() in order to reflect that.

The media entity actual init happens during entity register,
at media_device_register_entity(). We should move init of
num_links and num_backlinks to it.

have more than one type.

So, rename the field as function.

we have real case drivers using it.

No functional changes.

1809510715 [media] media: get rid of unused "extra_links" param on media_entity_init()
Currently, media_entity_init() creates an array with the links,
allocated at init time. It provides a parameter (extra_links)
that would allocate more links than the current needs, but this
is not used by any driver.

As we want to be able to do dynamic link allocation/removal,
we'll need to change the implementation of the links. So,
before doing that, let's first remove that extra unused
parameter, in order to cleanup the interface first.

df9ecb0cad [media] vb2: drop v4l2_format argument from queue_setup
The queue_setup callback has a void pointer that is just for V4L2
and is the pointer to the v4l2_format struct that was passed to
VIDIOC_CREATE_BUFS. The idea was that drivers would use the information
from that struct to buffers suitable for the requested format.

After the vb2 split series this pointer is now a void pointer,
which is ugly, and the reality is that all existing drivers will
effectively just look at the sizeimage field of v4l2_format.

To make this more generic the queue_setup callback is changed:
the void pointer is dropped, instead if the *num_planes argument
is 0, then use the current format size, if it is non-zero, then
it contains the number of requested planes and the sizes array
contains the requested sizes. If either is unsupported, then return
-EINVAL, otherwise use the requested size(s).

create a subdir at linux/platform_data and move the headers to that

And the references fixed with this script:
    MAIN_DIR="linux/platform_data/"
    PREV_DIR="media/"
    DIRS="media/"

    echo "Checking affected files" >&2
    for i in $DIRS; do
	for j in $(find include/$MAIN_DIR/$i -type f -name '*.h'); do
		 n=`basename $j`
		git grep -l $n

In order to have subsytem agnostic media bus format definitions we've
moved media bus definition to include/uapi/linux/media-bus-format.h and
prefixed values with MEDIA_BUS_FMT instead of V4L2_MBUS_FMT.

Reference new definitions in all platform drivers.

cba63cf8f9 [media] vivid: default to single planar device instances
The default used to be that the first vivid device instance was
single planar, the second multi planar, the third single planar, etc.

However, that turned out to be unexpected and awkward. Change the
driver to always default to single planar.

Pull media updates from Mauro Carvalho Chehab:

 - new IR driver: hix5hd2-ir

 - the virtual test driver (vivi) was replaced by vivid, with has an
   almost complete set of features to emulate most v4l2 devices and
   properly test all sorts of userspace apps

 - the as102 driver had several bugs fixed and was properly split into a
   frontend and a core driver.  With that, it got promoted from staging
   into mainstream

 - one new CI driver got added for CIMaX SP2/SP2HF (sp2 driver)

 - one new frontend driver for Toshiba ISDB-T/ISDB-S demod (tc90522)

 - one new PCI driver for ISDB-T/ISDB-S (pt3 driver)

 - saa7134 driver got support for go7007-based devices

 - added a new PCI driver for Techwell 68xx chipsets (tw68)

 - a new platform driver was added (coda)

 - new tuner drivers: mxl301rf and qm1d1c0042

 - a new DVB USB driver was added for DVBSky S860 & similar devices

 - added a new SDR driver (hackrf)

 - usbtv got audio support

 - several platform drivers are now compiled with COMPILE_TEST

 - a series of compiler fixup patches, making sparse/spatch happier with
   the media stuff and removing several warnings, especially on those
   platform drivers that didn't use to compile on x86

 - Support for several new modern devices got added

 - lots of other fixes, improvements and cleanups

19f94f9700 v4l2-pci-skeleton: Only build if PCI is available
Currently arm64 does not support PCI but it does support v4l2. Since the
PCI skeleton driver is built unconditionally as a module with no dependency
on PCI this causes build failures for arm64 allmodconfig. Fix this by
defining a symbol VIDEO_PCI_SKELETON for the skeleton and conditionalising
the build on that.

2a9ec37311 [media] v4l2-ctrls: use ptrs for all but the s32 type
Rather than having two unions for all types just keep 'val' and
'cur.val' and use the p_cur and p_new unions to access all others.

The only reason for keeping 'val' and 'cur.val' is that it is used
all over, so converting this as well would be a huge job.
