Lars-Peter Clausen d42010a1d2 [media] adv7604: Add adv7611 support
This patch adds support for the Analog Devices ADV7611 HDMI receiver.
The adv7611 is quite similar to the adv7604. It has only one instead of four
HDMI inputs and no analog frontend though. Also some register bits have been
shuffled around, but large parts of their register maps are compatible.

Laurent Pinchart 535ec214e2 [media] mt9p031: Fix BLC configuration restore when disabling test pattern
Auto BLC and BLC digital offset are disabled when enabling the test
pattern and must be restored when disabling it. The driver does so by
calling the set control handler on the auto BLC and BLC offset controls,
but this programs the hardware with the new value of those controls, not
the current value. Fix this by writing to the registers directly.

Laurent Pinchart 8bf54c4321 [media] mt9p031: Really disable Black Level Calibration in test pattern mode
The digital side of the Black Level Calibration (BLC) function must be
disabled when generating a test pattern to avoid artifacts in the image.
The driver disables BLC correctly at the hardware level, but the feature
gets reenabled by v4l2_ctrl_handler_setup() the next time the device is
powered on.

Fix this by marking the BLC controls as inactive when generating a test
pattern, and ignoring control set requests on inactive controls.

   - usual driver enhancements, new board additions and misc fixups"

[ NOTE! This merge effective drops commit 4329b93b28 ("of: Reduce
  indentation in of_graph_get_next_endpoint").

  The of_graph_get_next_endpoint() function was moved and renamed by
  commit fd9fdb78a9 ("[media] of: move graph helpers from
  drivers/media/v4l2-core to drivers/of").  It was originally called
  v4l2_of_get_next_endpoint() and lived in the file
  drivers/media/v4l2-core/v4l2-of.c.

  In that original location, it was then fixed to support empty port
  nodes by commit b9db140c1e ("[media] v4l: of: Support empty port
  nodes"), and that commit clashes badly with the dropped "Reduce
  intendation" commit.  I had to choose one or the other, and decided
  that the "Support empty port nodes" commit was more important ]

Sylwester Nawrocki 814b4dd9aa [media] V4L: Add driver for s5k6a3 image sensor
This patch adds subdev driver for Samsung S5K6A3 raw image sensor.
As it is intended at the moment to be used only with the Exynos
FIMC-IS (camera ISP) subsystem it is pretty minimal subdev driver.
It doesn't do any I2C communication since the sensor is controlled
by the ISP and its own firmware.
This driver, if needed, can be updated in future into a regular
subdev driver where the main CPU communicates with the sensor
directly.

Philipp Zabel fd9fdb78a9 [media] of: move graph helpers from drivers/media/v4l2-core to drivers/of
This patch moves the parsing helpers used to parse connected graphs
in the device tree, like the video interface bindings documented in
Documentation/devicetree/bindings/media/video-interfaces.txt, from
drivers/media/v4l2-core/v4l2-of.c into drivers/of/base.c.

This allows to reuse the same parser code from outside the V4L2
framework, most importantly from display drivers.
The functions v4l2_of_get_next_endpoint, v4l2_of_get_remote_port,
and v4l2_of_get_remote_port_parent are moved. They are renamed to
of_graph_get_next_endpoint, of_graph_get_remote_port, and
of_graph_get_remote_port_parent, respectively.
Since there are not that many current users yet, switch all of
them to the new functions right away.

Martin Bugge ce2d2b2d7a [media] adv7842: platform-data for Hotplug Active (HPA) manual/auto
This applies to HDMI-map register 0x69.
So far we have been using HPA manual mode.
This way we had control of HPA which could be
set after EDID had been programmed.

Using a Mac Mini with mini-displayport to DVI-D converter as source
caused the adv7842 to lock up and fail to detect any further signals.

After experimenting with different configurations it was found that
using the HPA auto mode and in addition letting RX-termination
be controlled by HPA prevented this error from occuring.

I was not able to re-create this problem on the adv7604.

Using variable length array in s5k5baf_write_arr_seq caused
an implicit assumption that i2c sequences should be short.
The patch rewrites the function so it can handle sequences
of any length and does not use variable length array.

Martin Bugge 3c4da74fe5 [media] adv7842: 625/525 line standard jitter fix
Both the PAL and NTSC standards are interlaced where a
frame consist of two fields. Total number of lines in a frame in both systems
are an odd number so the two fields will have different length.

In the 625 line standard ("PAL") the odd field of the frame is transmitted first,
while in the 525 standard ("NTSC") the even field is transmitted first.

This adds the possibility to change output config between the fields and standards.

This setting will reduce the "format-jitter" on the signal sent by the pixelport
moving the difference between the fields to vertical front/back-porch only.

Martin Bugge a62c621670 [media] adv7511: disable register reset by HPD
Whenever the hotplug pin is pulled low the chip resets a whole bunch
of registers. It turns out that this can be turned off on the adv7511.
Do so, as this 'feature' introduces race conditions in setting up
registers, particular when the hotplug pin bounces a lot.

Hans Verkuil a03636cb21 [media] omap24xx/tcm825x: move to staging for future removal
The omap24xx driver and the tcm825x sensor driver are the only two
remaining drivers to still use the old deprecated v4l2-int-device API.

Nobody maintains these drivers anymore. But unfortunately the v4l2-int-device
API is used by out-of-tree drivers (MXC platform). This is a very bad situation
since as long as this deprecated API stays in the kernel there is no reason for
those out-of-tree drivers to convert.

This patch moves v4l2-int-device and the two drivers that depend on it to
staging in preparation for their removal.

If someone would be interested in getting these drivers to work, then start with
this since it's not very far from the state where they used to work:

<URL:http://vihersipuli.retiisi.org.uk/cgi-bin/gitweb.cgi?p=~sailus/linux-omap/.git;a=summary>

The branch is n800-cam. Porting to up-to-date APIs can then be done. David
might have done some work in that area, so check with him first.

Pull media updates from Mauro Carvalho Chehab:
 "This series include:
   - a new Remote Controller driver for ST SoC with the corresponding DT
     bindings
   - a new frontend (cx24117)
   - a new I2C camera flash driver (lm3560)
   - a new mem2mem driver for TI SoC (ti-vpe)
   - support for Raphael r828d added to r820t driver
   - some improvements on buffer allocation at VB2 core
   - usual driver fixes and improvements

  PS this time, we have a smaller number of patches.  While it is hard
  to pinpoint to the reasons, I believe that it is mainly due to:

   1) there are several patch series ready, but depending on DT review.
      I decided to grant some extra time for DT maintainers to look on
      it, as they're expecting to have more time with the changes agreed
      during ARM mini-summit and KS.  If they can't review in time for
      3.14, I'll review myself and apply for the next merge window.

   2) I suspect that having both LinuxCon EU and LinuxCon NA happening
      during the same merge window affected the development
      productivity, as several core media developers participated on
      both events"

v4l2-common.c contained a bunch of dv-timings related functions.
Move that to the new v4l2-dv-timings.c which is a more appropriate
place for them.
There aren't many drivers that do HDTV, so it is a good idea to separate
common code related to that into a module of its own.

Mauro Carvalho Chehab 6a084d6b3d [media] saa7115: Don't use a dynamic array
At least on s390, gcc complains about that:
    drivers/media/i2c/saa7115.c: In function 'saa711x_detect_chip.constprop.2':
    drivers/media/i2c/saa7115.c:1647:1: warning: 'saa711x_detect_chip.constprop.2' uses dynamic stack allocation [enabled by default]

While for me the above report seems utterly bogus, as the
compiler should be optimizing saa711x_detect_chip, merging
it with saa711x_detect_chip and changing:
	char chip_ver[size - 1];
to
	char chip_ver[16];

because this function is only called on this code snippet:
	char name[17];
	...
	ident = saa711x_detect_chip(client, id, name, sizeof(name));

It seems that gcc is not optimizing it, at least on s390.

As getting rid of it is easy, let's do it.

Jon Arne Jørgensen 241d89fce7 [media] saa7115: Add register setup and config for gm7113c
The gm7113c chip is similar to the original saa7113 chip, so I try to
re-use most of the saa7113 specific setup-/configuration registers.
According to the datasheet, the gm7113c chip has not implemented
any register-addresses after 0x1f, so I add a new entry to for the chip
to the saa711x_has_reg function.
The devices I've seen using this chip will fail to get stable video-sync
if these registers are not zeroed:
	R_14_ANAL_ADC_COMPAT_CNTL
	R_15_VGATE_START_FID_CHG
	R_16_VGATE_STOP
	R_17_MISC_VGATE_CONF_AND_MSB
The saa711x_set_v4lstd is updated to send a simpler configuration-table
to avoid setting these registers.
