Pull second batch of media updates from Mauro Carvalho Chehab:
 "This is the second part of the media patches.  It contains the media
  controller next generation patches, with is the result of one year of
  discussions and development.  It also contains patches to enable media
  controller support at the DVB subsystem.

  The goal is to improve the media controller to allow proper support
  for other types of Video4Linux devices (radio and TV ones) and to
  extend the media controller functionality to allow it to be used by
  other subsystems like DVB, ALSA and IIO.

  In order to use the new functionality, a new ioctl is needed
  (MEDIA_IOC_G_TOPOLOGY).  As we're still discussing how to pack the
  struct fields of this ioctl in order to avoid compat32 issues, I
  decided to add a patch at the end of this series commenting out the
  new ioctl, in order to postpone the addition of the new ioctl to the
  next Kernel version (4.6).

  With that, no userspace visible changes should happen at the media
  controller API, as the existing ioctls are untouched.  Yet, it helps
  DVB, ALSA and IIO developers to develop and test the patches adding
  media controller support there, as the core will contain all required
  internal changes to allow adding support for devices that belong to
  those subsystems"

Mauro Carvalho Chehab 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.

Mauro Carvalho Chehab 3efdf62c5f [media] media: use macros to check for V4L2 subdev entities
Instead of relying on media subtype, use the new macros to detect
if an entity is a subdev or an A/V DMA entity.

Please note that most drivers assume that there's just AV_DMA or
V4L2 subdevs. This is not true anymore, as we've added MC support
for DVB, and there are plans to add support for ALSA and FB/DRM
too.

Ok, on the current pipelines supported by those drivers, just V4L
stuff are there, but, assuming that some day a pipeline that also
works with other subsystems will ever added, it is better to add
explicit checks for the AV_DMA stuff.

The omap4iss driver initializes the entities and creates the pads links
before the entities are registered with the media device. This does not

made after the entities registration.

Javier Martinez Canillas d10c98949d [media] media: use entity.graph_obj.mdev instead of .parent
The struct media_entity has a .parent field that stores a pointer
to the parent struct media_device. But recently a media_gobj was
embedded into the entities and since struct media_gojb already has
a pointer to a struct media_device in the .mdev field, the .parent
field becomes redundant and can be removed.

This patch replaces all the usage of .parent by .graph_obj.mdev so
that field will become unused and can be removed on a later patch.

No functional changes.

The transformation was made using the following coccinelle spatch:

Mauro Carvalho Chehab 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.

Hans Verkuil 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).

Arnd Bergmann 0dbf41a3c8 [media] staging: media: lirc: Replace timeval with ktime_t in lirc_parallel.c
'struct timeval tv' and 'struct timeval now' is used to calculate the
elapsed time. 'LIRC_SFH506_DELAY' is a delay t_phl in usecs.

32-bit systems using 'struct timeval' will break in the year 2038,
so we have to replace that code with more appropriate types.
This patch changes the lirc_parallel.c file of  media: lirc driver
to use ktime_t.

ktime_get() is  better than using do_gettimeofday(),
because it uses the monotonic clock. ktime_sub is used
to subtract two ktime variables. ktime_to_us() is used to
convert ktime to microsecond.

New ktime_t variable timeout, is added in lirc_off(),to improve
clarity. Introduced a new ktime_t variable in lirc_lirc_irq_handler()
function, to avoid the use of signal variable for storing
seconds in the first part of this function as later it uses
a time unit that is defined by the global "timer" variable.
This makes it more clear.

ktime_set() is used to set a value in seconds to a value in
nanosecond so that ktime_compare() can be used appropriately.
ktime_compare() is used to compare two ktime values.
ktime_add_ns() is used to increment a ktime value by 1 sec.

One comment is also shifted a line up, as it was creating a 80
character warning.

Build tested it. Also tested it with sparse.

going backwards is also removed. Intialization to static
variable is also removed. ktime_to_us() is used to convert
ktime_t to microsecond value. deltv is changed to delkt, a
ktime_t type varibale from long to assign the ktime_sub value
directly. ktime_compare is used to compare delkt with 15
seconds, which is changed to a nanosecond value by using
ktime_set().

Laurent Pinchart 769161fd2d [media] media: omap4iss: csi2: Fix IRQ handling when stopping module
When stopping the CSI2 receiver the s_stream handler will wait for the
IRQ handler to notice the stop request. The receiver, automatically
disabled by the hardware after each frame, is then not reenabled by the
IRQ handler as it returns immediately.

As the IRQ handler check is performed before handling the context IRQ,
the context IRQ source isn't cleared, and the CSI2 IRQ is then fired
again immediately. The IRQ handler then fails to notice that the module
is being stopped, processes the IRQ normally and reenables the CSI2
hardware.

The problem goes unnoticed at stream stop time, but depending on the IRQ
and s_stream scheduling timings, the CSI2 receiver can end up being
hanged and will not produce any interrupt the next time it gets enabled,
despite being soft-reset then.

Fix this by checking for module stop after clearing the context IRQ
source.

Nate Weibley 425e186847 [media] omap4iss: Fix overlapping luma/chroma planes
The chroma data base address for NV12 formatted data should begin offset
rows*bytes_per_row from the base address for luminance data. We were OBO
causing a stripe of green pixels at the bottom of the frame.

Correct typo in the name of the type given to sizeof.  Because it is the
size of a pointer that is wanted, the typo has no impact on compilation or

This problem was found using Coccinelle (http://coccinelle.lip6.fr/).  The
semantic patch used can be found in message 0 of this patch series.

Mauro Carvalho Chehab eb4b0ec75e [media] include/media: move platform_data to linux/platform_data/media
Let's not mix platform_data headers with the core headers. Instead, let's
create a subdir at linux/platform_data and move the headers to that
common place, adding it to MAINTAINERS.

The headers were moved with:
	mkdir include/linux/platform_data/media/; git mv include/media/gpio-ir-recv.h include/media/ir-rx51.h include/media/mmp-camera.h include/media/omap1_camera.h include/media/omap4iss.h include/media/s5p_hdmi.h include/media/si4713.h include/media/sii9234.h include/media/smiapp.h include/media/soc_camera.h include/media/soc_camera_platform.h include/media/timb_radio.h include/media/timb_video.h include/linux/platform_data/media/

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 $n
	done
    done|sort|uniq >files && (
	echo "Handling files..." >&2;
	echo "for i in \$(cat files|grep -v Documentation); do cat \$i | \\";
	(
		cd include/$MAIN_DIR;
		for j in $DIRS; do
			for i in $(ls $j); do
				echo "perl -ne 's,(include [\\\"\\<])$PREV_DIR($i)([\\\"\\>]),\1$MAIN_DIR$j\2\3,; print \$_' |\\";
			done;
		done;
		echo "cat > a && mv a \$i; done";
	);
	echo "Handling documentation..." >&2;
	echo "for i in MAINTAINERS \$(cat files); do cat \$i | \\";
	(
		cd include/$MAIN_DIR;
		for j in $DIRS; do
			for i in $(ls $j); do
				echo "  perl -ne 's,include/$PREV_DIR($i)\b,include/$MAIN_DIR$j\1,; print \$_' |\\";
			done;
