Hans Verkuil 2169e6daa1 media: media/pci: don't set description for ENUM_FMT
The V4L2 core sets the description for the driver in order to ensure
consistent naming.

So drop the strscpy of the description in drivers. Also remove any
description strings in driver-internal structures since those are
no longer needed.

Hans Verkuil 2161536516 media: media/pci: set device_caps in struct video_device
Instead of filling in the struct v4l2_capability device_caps
field, fill in the struct video_device device_caps field.

That way the V4L2 core knows what the capabilities of the
video device are.

But this only really works if all drivers use this, so convert
all pci drivers in this patch.

Tested with cx88-blackbird and ivtv PVR-350.

Ezequiel Garcia cd63c0288f media: sta2x11: Add video_device and vb2_queue locks
Currently, this driver does not serialize its video4linux
ioctls, which is a bug, as race conditions might appear.

In addition, video_device and vb2_queue locks are now both
mandatory. Add them, and implement wait_prepare and
wait_finish.

To stay on the safe side, this commit uses a single mutex
for both locks. Better latency can be obtained by separating
these if needed.

Geert Uytterhoeven 4cff79e933 media: Remove depends on HAS_DMA in case of platform dependency
Remove dependencies on HAS_DMA where a Kconfig symbol depends on another
symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST".
In most cases this other symbol is an architecture or platform specific
symbol, or PCI.

Generic symbols and drivers without platform dependencies keep their
dependencies on HAS_DMA, to prevent compiling subsystems or drivers that
cannot work anyway.

This simplifies the dependencies, and allows to improve compile-testing.

Note:
  - The various VIDEOBUF*DMA* symbols had to loose their dependencies on
    HAS_DMA, as they are selected by several individual drivers.

Arvind Yadav 0bade8b543 media: sta2x11: Use gpio_is_valid() and remove unnecessary check
Replace the manual validity checks for the GPIO with the
gpio_is_valid().

In vip_gpio_reserve(), Error checking for gpio pin is not correct.
If pwr_pin = -1, It will return 0. This should be return an error.

In sta2x11_vip_init_one(), Error checking for gpio 'reset_pin'
is unnecessary. Because vip_gpio_reserve() is also checking for
valid gpio pin. So removed extra error checking for gpio 'reset_pin'.

Note that the memops functions now get a struct device pointer instead of

This code is now a lot cleaner.

The s_std ioctl was broken in this driver, partially due to the

The handling of V4L2_STD_ALL has been rewritten to just call querystd
and the new standard is now stored correctly.

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).

As there currently don't seem to be any users of the video ops format
operations those are removed as well in this patch.

Also set the V4L2_SUBDEV_FL_HAS_DEVNODE flag for the subdevice so it is
possible to create a subdevice device node.

Since the driver now depends on VIDEO_V4L2_SUBDEV_API all drivers which
select the driver need to depend on that symbol as well.

Laurent Pinchart d52e238136 [media] v4l: Support extending the v4l2_pix_format structure
The v4l2_pix_format structure has no reserved field. It is embedded in
the v4l2_framebuffer structure which has no reserved fields either, and
in the v4l2_format structure which has reserved fields that were not
previously required to be zeroed out by applications.

To allow extending v4l2_pix_format, inline it in the v4l2_framebuffer
structure, and use the priv field as a magic value to indicate that the
application has set all v4l2_pix_format extended fields and zeroed all
reserved fields following the v4l2_pix_format field in the v4l2_format
structure.

The availability of this API extension is reported to userspace through
the new V4L2_CAP_EXT_PIX_FORMAT capability flag. Just checking that the
priv field is still set to the magic value at [GS]_FMT return wouldn't
be enough, as older kernels don't zero the priv field on return.

To simplify the internal API towards drivers zero the extended fields
and set the priv field to the magic value for applications not aware of
the extensions.

Hans Verkuil e37559b22c [media] vb2: stop_streaming should return void
The vb2 core ignores any return code from the stop_streaming op.
And there really isn't anything it can do anyway in case of an error.
So change the return type to void and update any drivers that implement it.

The int return gave drivers the idea that this operation could actually
fail, but that's really not the case.

The pwc amd sdr-msi3101 drivers both had this construction:

        if (mutex_lock_interruptible(&s->v4l2_lock))
                return -ERESTARTSYS;

This has been updated to just call mutex_lock(). The stop_streaming op
expects this to really stop streaming and I very much doubt this will
work reliably if stop_streaming just returns without really stopping the
DMA.

Hans Verkuil 9c0863b1cc [media] vb2: call buf_finish from __queue_cancel
If a queue was canceled, then the buf_finish op was never called for the
pending buffers. So add this call to queue_cancel. Before calling buf_finish
set the buffer state to PREPARED, which is the correct state. That way the
states DONE and ERROR will only be seen in buf_finish if streaming is in
progress.

Since buf_finish can now be called from non-streaming state we need to
adapt the handful of drivers that actually need to know this.

Greg Kroah-Hartman 4c62e9764a Drivers: media: remove __dev* attributes.
CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Mauro Carvalho Chehab fccea74ff8 [media] Kconfig: merge all customise options into just one
Instead of having 3 options to allow customizing the media
sub-drivers (tuners, I2C drivers, frontends), merge all of
them into just one.

That simplifies the life for users, as they can just keep
this untouched.

Life for developers is also simpler, as there's now just
one Kconfig item to remember, for the ancillary sub-drivers
providing supports for chips that could change from one
board design to another.
