This driver exposes preview mode operation of the S5K6AAFX sensor with
embedded SoC ISP. The native capture (snapshot) operation mode is not
supported.
Following controls are available:
manual/auto exposure and gain, power line frequency (anti-flicker),
saturation, sharpness, brightness, contrast, white balance temperature,
color effects, horizontal/vertical image flip, frame interval,
auto white balance.
RGB component gains are currently exposed through private controls.Reviewed-by: Sakari Ailus

The most important change in this patch is direct linking to struct
soc_camera_link via the client->dev.platform_data pointer. This makes most
of the soc-camera client drivers also usable outside of the soc-camera
framework. After this change all what is needed for these drivers to
function are inclusions of soc-camera headers for some convenience macros,
suitably configured platform data, which is anyway always required, and
loaded soc-camera core module for library functions. If desired, these
library functions can be made generic in the future and moved to a more
neutral location.The only two client drivers, that still depend on soc-camera are:
mt9t031: it uses struct video_device for its PM. Since no hardware is
available, alternative methods cannot be tested.ov6650: it uses struct soc_camera_device to pass its sense data back to
the bridge driver. A generic v4l2-subdevice approach should be developed
to perform this.Signed-off-by: Guennadi Liakhovetski

VIDIOC_G_STD can return the current TV-norm to the user in one of two ways:
if an .vidioc_g_std() ioctl operation is provided by the driver, it is
called, otherwise the value ot the .current_norm field of struct
video_device is returned. Since subdevice drivers currently have no access
to struct video_device objects, the only way to provide this information to
the user is by implementing a .g_std() method.Signed-off-by: Guennadi Liakhovetski

Currently only very few drivers actually use video_device nodes, embedded

With the new subdevice media-bus configuration methods bus-width is not
configured along with other bus parameters, instead, it is derived from

The pretty much brings in the kitchen sink along
with it, so it should be avoided wherever reasonably possible in
terms of being included from other commonly used
files, as it results in a measureable increase on compile times.The worst culprit was probably device.h since it is used everywhere.
This file also had an implicit dependency/usage of mutex.h which was
masked by module.h, and is also fixed here at the same time.There are over a dozen other headers that simply declare the
struct instead of pulling in the whole file, so follow their lead
and simply make it a few more.Most of the implicit dependencies on module.h being present by
these headers pulling it in have been now weeded out, so we can
finally make this change with hopefully minimal breakage.Signed-off-by: Paul Gortmaker

Signed-off-by: Mauro Carvalho Chehab -
FIELD signal is used for indicating frame field type to the frame grabber
in interlaced scan mode, as specified in ITU-R BT.601 standard.
In normal operation mode FIELD = 0 selects Field1 (odd) and FIELD = 1
selects Field2 (even). When the FIELD signal is inverted it's the other
way around.Add corresponding flags for configuring the FIELD signal polarity,
V4L2_MBUS_FIELD_EVEN_HIGH for the standard (non-inverted) case and
V4L2_MBUS_FIELD_EVEN_LOW for inverted case.Also add a comment about usage of V4L2_MBUS_[HV]SYNC* flags for
the hardware that uses [HV]REF signals.Signed-off-by: Sylwester Nawrocki

The problem tackled in this patch is how to handle volatile autoclusters
correctly. A volatile autocluster is a cluster of related controls where one
control is the control that toggles between manual and auto mode and the other
controls are the values for the manual mode. For example autogain and gain,
autoexposure and exposure, etc.If the hardware lets you read out the automatically calculated manual values
while in automode, then those manual controls should be marked volatile.gain value as calculated by the autogain circuitry, then you would mark the
gain control as volatile (i.e. continuously changing).The question in such use cases is what to do when switching from the auto
mode to the manual mode. Should we switch to the last set manual values or
should the volatile values be copied and used as the initial manual values.For example: suppose the mode is manual gain and gain is set to 5. Then
autogain is turned on and the gain is set by the hardware to 2. Finally
the user switches back to manual gain. What should the gain be? 2 or 5?After a long discussion the decisions was made to keep the last value as
calculated by the auto mode (so 2 in the example above).The reason is that webcams that do such things will adapt themselves to
the current light conditions and when you switch back to manual mode you
expect that you keep the same picture. If you would switch back to old
manual values, then that would give you a suddenly different picture,
which is jarring for the user.Additionally, this would be difficult to implement in applications that
store and restore the control values at application exit and start.If you want to keep the old manual values when you switch from auto to
manual, then there would have to be a way for applications to get hold
of those old values while in auto mode, but there isn't.So this patch will do all the heavy lifting in v4l2-ctrls.c: if you go
from auto mode to manual mode and the manual controls are volatile, then
g_volatile_ctrl will be called to get the current values for the manual
controls before switching to manual mode.Signed-off-by: Hans Verkuil

Fast-forward merge with Linus to be able to merge patches
based on more recent version of the tree. -
It was pointed out by 'make versioncheck' that some includes of
linux/version.h are not needed in include/.
This patch removes them.When I last posted the patch, the ceph bit was ACK'ed by Sage Weil, so
I've added that below.The pwc-ioctl change generated quite a bit of discussion about V4L version
numbers in general, but as far as I can tell, no concensus was reached on
what the long term solution should be, so in the mean time I think we
could start by just removing the unneeded include, which is why I'm
resending the patch with that hunk still included.Signed-off-by: Jesper Juhl
