There is no need to check same bit before setting it, since we
always end up with a bit set. Remove some of the tests and make
set unconditional, in every place where all that needs to be done

Sylwester Nawrocki 4c8f0629f5 [media] exynos4-is: Make fimc-lite independent of struct fimc_sensor_info
Make the sensor subdevs host_data hold a pointer to struct fimc_source_info,
which is defined in the driver's public header, rather than a pointer to
struct fimc_sensor_info which is specific to exynos4-is media device driver.
The purpose of this change is to allow easier reuse of the fimc-lite module
in the exynos5-is driver, which should similarly store a pointer to struct
fimc_source_info instance in the sensor's subdev host_data.

Using 'i' for the guard interval temporary var is a bad idea, as
'i' is generally used by "anonymous" indexes.
Let's rename modulation, fec and guard interval temp vars with
a meaningful name, as that makes easier to understand the code

configuration of TDA8290 tuner (it's not used by any other driver).
But with the new configuration options of tda8290 driver (no_i2c_gate

config struct to drivers.

Mauro Carvalho Chehab 48a8a03b58 [media] cx88: kernel bz#9476: Fix tone setting for Nova-S+ model 92001
Hauppauge Nova-S-Plus DVB-S model 92001 does not lock on horizontal
polarisation. According with the info provided at the BZ, model
92002 does.

The difference is that, on model 92001, the tone select is done via
isl6421, while, on other devices, this is done via cx24123 code.
This patch adds a way to override the demod's set_tone at isl6421
driver. In order to avoid regressions, the override is enabled
only for cx88 Nova S plus model 92001. For all other models and
devices, the set_tone is provided by the demod driver.

Patch originally proposed at bz@9476[1] by Michel Meyers and
John Donoghue but applying the original patch would break support
for all other devices based on isl6421.

The FIMC-LITE output DMA allows to configure different YUV order
than the order at the camera input interface. Thus there is some
limited colorspace conversion possible. This patch makes the
color format variable be per FIMC-LITE input/output, rather than
a global per device. This also fixes incorrect behavior where
color format at the FIMC-LITE.N subdev's source pad is modified

Sylwester Nawrocki e781bbe3fe [media] exynos4-is: Add fimc-is subdevs registration
This patch adds support for registration of the FIMC-IS device
represented by the FIMC-IS-ISP subdev to the top level media device
driver. The FIMC-IS subsystem is available on Exynos4x12 SoCs which
support only device tree based booting.

Sylwester Nawrocki b8d9834a12 [media] exynos4-is: Add common FIMC-IS image sensor driver
This patch adds a common image sensor driver and Makefile/Kconfig
to enable compilation of the whole IS driver.
The sensor subdev driver currently only handles an image sensor's
power supplies and reset signal. There is no I2C communication as
it is handled by the ISP's firmware.

Sylwester Nawrocki da114376d3 [media] exynos4-is: Add FIMC-IS ISP I2C bus driver
This patch adds the ISP I2C bus controller driver files.
Creating a standard I2C bus adapter, even if the driver doesn't
actually communicate with the hardware and it is instead
controlled by the ISP firmware running on the Cortex-A5, allows
to use standard hardware description in the device tree. As the
sensor would have actually had a standard V4L2 sub-device driver
run on the host CPU.
This approach allows to adapt the driver with a relatively small
effort should the Imaging Subsystem architecture change so that
the I2C bus is handled by the host's CPU OS, rather than the
internal FIMC-IS ARM CPU firmware. The image sensor driver could
be a standard I2C client driver, as in case of most existing
image sensors.

Sylwester Nawrocki 9a761e4368 [media] exynos4-is: Add Exynos4x12 FIMC-IS driver
This patch adds a set of core files of the Exynos4x12 FIMC-IS
V4L2 driver. This includes main functionality like allocating
memory, loading the firmware, FIMC-IS register interface and
host CPU <-> IS command and error code definitions.
The driver currently exposes a single subdev named FIMC-IS-ISP,
which corresponds to the FIMC-IS ISP and DRC IP blocks.
The FIMC-IS-ISP subdev currently supports only a subset of user
controls. For other controls we need several extensions at the
V4L2 API. The supported standard controls are:
brightness, contrast, saturation, hue, sharpness, 3a_lock,
exposure_time_absolute, white_balance_auto_preset,
iso_sensitivity, iso_sensitivity_auto, exposure_metering_mode.

Sylwester Nawrocki 88fa8311ee [media] s5p-fimc: Add support for ISP Writeback data input bus type
A second sink pad is added to each FIMC.N subdev that will be used
to link it to the FIMC-IS-ISP subdev. Only V4L2_MBUS_FMT_YUV10_1X30
format is supported at this pad (FIMC_SD_PAD_SINK_FIFO).
The routine checking for mismatch in the image formats at sides of
the links is updated to account for the fact FIMC.X subdevs now have
sink pads at the pad indexes 0, 1 and source pad at pad index 2.
If link to FIMC.X pad 1 is activated we switch FIMC input data bus
type to the ISP Writeback. Only a single active link to FIMC.X pad 0
or 1 will be allowed at any time.

Sylwester Nawrocki 2b13f7d4e3 [media] s5p-fimc: Add device tree based sensors registration
The sensor (I2C and/or SPI client) devices are instantiated by their
corresponding control bus drivers. Since the I2C client's master clock
is often provided by a video bus receiver (host interface) or other
than I2C/SPI controller device, the drivers of those client devices
are not accessing hardware in their driver's probe() callback. Instead,
after enabling clock, the host driver calls back into a sub-device
when it wants to activate them. This pattern is used by some in-tree
drivers and this patch also uses it for DT case. This patch is intended
as a first step for adding device tree support to the S5P/Exynos SoC
camera drivers. The second one is adding support for asynchronous
sub-devices registration and clock control from sub-device driver
level. The bindings shall not change when asynchronous probing support
is added.

radio->curfreq to out of range value (lines 395-396) and calls
amradio_set_freq() to set this frequency on device without any
out-of-range checks.

Patch protects from setting up frequency on device to incorrect value
moving clamp_t check inside amradio_set_freq. With this patch we can
call amradio_set_freq() with out of range frequency from any place.

Separate it and move it to em28xx_hint_board() which already contains the board

This way, we have all board hints at a common place which makes it easier
to extend the code and reduces the risk of regressions.
It also makes it possible again to use the boards EM2750_BOARD_DLCW_130,

Frank Schaefer 72cc9ba39a [media] em28xx: ignore isoc DVB USB endpoints with wMaxPacketSize = 0 bytes for all alt settings
Some devices without DVB support (such as the "Terratec Grabby" and
"Easycap DC-60") provide isochronous DVB USB endpoints with wMaxPacketSize set
to 0 bytes for all alt settings.
Ignore these endpoints and avoid registering a DVB device node and loading the
DVB driver extension.

Frank Schaefer a3ea4bf98b [media] em28xx: add support for em25xx i2c bus B read/write/check device operations
The webcam "SpeedLink VAD Laplace" (em2765 + ov2640) uses a special algorithm
for i2c communication with the sensor, which is connected to a second i2c bus.
We don't know yet how to find out which devices support/use it.
It's very likely used by all em25xx and em276x+ bridges.
Tests with other em28xx chips (em2820, em2882/em2883) show, that this
algorithm always succeeds there although no slave device is connected.
The algorithm likely also works for real i2c client devices (OV2640 uses SCCB),
because the Windows driver seems to use it for probing Samsung and Kodak
sensors.

Hans de Goede 35ccecef6e [media] [REGRESSION] bt8xx: Fix too large height in cropcap
Since commit a1fd287780c8e91fed4957b30c757b0c93021162:
"[media] bttv-driver: fix two warnings"
cropcap.defrect.height and cropcap.bounds.height for the PAL entry are 32
resp 30 pixels too large, if a userspace app (ie xawtv) actually tries to use
the full advertised height, the resulting image is broken in ways only a
screenshot can describe.
The cause of this is the fix for this warning:
drivers/media/pci/bt8xx/bttv-driver.c:308:3: warning: initialized field overwritten [-Woverride-init]
In this chunk of the commit:
@@ -301,11 +301,10 @@ const struct bttv_tvnorm bttv_tvnorms[] = {

                .name           = "NTSC",
Which replaces the overriding of cropcap.bounds.height initialization outside
of the CROPCAP macro (which also initializes it), with passing a
different sheight value to the CROPCAP macro.
There are 2 problems with this warning fix:
1) The sheight value is used twice in the CROPCAP macro, and the old code
   only changed one resulting value.
2) The old code increased the .cropcap.bounds.height value (and did not
   touch the .cropcap.defrect.height value at all) by 2, where as the fixed
   code increases it by 32, as the fixed code passes (576 + 2) + 0x20 - 2
   to the CROPCAP macro, but the + 0x20 - 2 is already done by the macro so
   now is done twice for .cropcap.bounds.height, and also is applied to
   .cropcap.defrect.height where it should not be applied at all.
This patch fixes this by adding an extraheight parameter to the CROPCAP entry
and using it for the PAL entry.

Hans Verkuil 106cf649d0 [media] tuner-core: don't set has_signal/get_afc if not supported
If the tuner frontend does not support get_rf_strength, then don't set
the has_signal callback. Ditto for get_afc.
Both callbacks overwrite the signal and afc fields of struct v4l2_tuner
but that should only happen if the tuner can actually detect this. If
it can't, then it should leave those fields alone so other subdevices
can try and detect the signal/afc.
This fixes the bug where the au8522 detected a signal and then tuner-core
overwrote it with 0 since the xc5000 tuner does not support get_rf_strength.

Hans Verkuil c7c54a988d [media] sony-btf-mpx: the MPX driver for the sony BTF PAL/SECAM tuner
The Sony BTF PG472Z has an internal MPX to deal with mono/stereo/bilingual
audio. This is split off from the wis-sony-tuner driver that is part of
the go7007 driver as it should be a separate i2c sub-device driver.
The wis-sony-tuner is really three i2c devices: a standard tuner, a tda9887
compatible demodulator and this mpx. After this patch the wis-sony-tuner
can be replaced by this driver and the standard tuner driver.

Hans Verkuil 73f35418a1 [media] v4l2-ioctl: check if an ioctl is valid
Just checking if the op exists isn't correct, you should check if the ioctl
is valid (which implies that the op exists as well).
One exception is g_std: if current_norm is non-zero, then the g_std op may be
absent. This sort of weird behavior is one of the reasons why I am trying to
get rid of current_norm.
This patch fixes the case where the g/s_std op is set, but these ioctls are
disabled. This can happen in drivers supporting multiple models, some that
have TV input (and support the STD API) and some that have a sensor (and do
not support the STD API). In the latter case qv4l2 would still show the
Standards combobox.

Andy Walls 6cd247ef22 [media] v4l2-ctrls: eliminate lockdep false alarms for struct v4l2_ctrl_handler.lock
When calling v4l2_ctrl_add_handler(), lockdep would detect a potential
recursive locking problem on a situation that is by design intended and
not a recursive lock.  This happened because all struct
v4l2_ctrl_handler.lock mutexes were created as members of the same lock
class in v4l2_ctrl_handler_init(), and v4l2_ctrl_add_handler() takes the
hdl->lock on two different v4l2_ctrl_handler instances.
This change breaks the large lockdep lock class for struct
v4l2_ctrl_handler.lock and breaks it into v4l2_ctrl_handler
instantiation specific lock classes with meaningful class names.
This will validly eliminate lockdep alarms for v4l2_ctrl_handler locking
validation, as long as the relationships between drivers adding v4l2
controls to their own handler from other v4l2 drivers' control handlers
remains straightforward.
struct v4l2_ctrl_handler.lock lock classes are created with names such
that the output of cat /proc/lockdep indicates where in the v4l2 driver
code v4l2_ctrl_handle_init() is being called on instantiations:
ffffffffa045f490 FD:   10 BD:    8 +.+...: cx2341x:1534:(hdl)->lock
ffffffffa0497d20 FD:   12 BD:    2 +.+.+.: saa7115:1581:(hdl)->lock

ffffffffa04fbc80 FD:   11 BD:    3 +.+.+.: wm8775:246:(&state->hdl)->lock
Some lock chains, that were previously causing the recursion alarms, are
now visible in the output of cat /proc/lockdep_chains:
irq_context: 0
[ffffffffa0497d20] saa7115:1581:(hdl)->lock

Hans Verkuil 505d04bdc4 [media] v4l2-ioctl: simplify debug code
The core debug code can now be simplified since all the write-only ioctls are
now const and will not modify the data they pass to the drivers.
So instead of logging write-only ioctls before the driver is called this can
now be done afterwards, which is cleaner when it comes to error reporting as
well.
This also fixes a logic error in the debugging code where there was one 'else'
too many.

This just adds dv_timings support without modifying existing dv_preset
support, although I had to refactor a little bit in order to share
hdmiphy_find_conf() between the preset and timings code.

Antti Palosaari b09e71a8de [media] it913x: fix pid filter
I just made commit: "dvb_usb_v2: rework USB streaming logic" that
breaks that driver PID filter.
it913x driver checks use of PID filter directly from DVB USB v2 core
internal variable "adap->pid_filtering" and stores it to own state.
Calling order of .pid_filter_ctrl() and .pid_filter() was changed
and due to that state was updated too late. Update state earlier.
TODO: checking PID filter usage from DVB USB v2 is not very good idea
as PID filter callbacks are called only when PID filter is enabled.

Control flow order changed a little bit. HW PID filter is now
disabled also when streaming is stopped - earlier it was just
set only when streaming was started.
Control flow is now:
* set streaming status bit
* submit USB streaming packets
* enable HW PID filter
* ask device to start streaming
* N x add PID to device HW PID filter
... streaming video ...
* N x remove PID from device HW PID filter
* ask device to stop streaming
* disable HW PID filter
* kill USB streaming packets
* clear streaming status bit
