[media] v4l: add enum_freq_bands support to tuner sub-device

2014-03-13T13:26:47+00:00

Add VIDIOC_ENUM_FREQ_BANDS, enumerate supported frequency bands,
IOCTL support for sub-device tuners too.

[media] v4l2: add VIDIOC_G/S_EDID support to the v4l2 core

2014-03-11T13:06:53+00:00

Support this ioctl as part of the v4l2 core. Use the new ioctl
name and struct v4l2_edid type in the existing core code.

[media] v4l2-subdev: Allow 32-bit compat ioctls

2014-02-24T13:57:14+00:00

Add support for 32-bit ioctls with v4l-subdev device nodes.

Rather than keep adding new ioctls to the list in v4l2-compat-ioctl32.c, just check
if the ioctl is a non-private V4L2 ioctl and if so, call the conversion code.

We keep forgetting to add new ioctls, so this is a more robust solution.

In addition extend the subdev API with support for a compat32 function to
convert custom v4l-subdev ioctls.

[media] v4l: Fix typo in v4l2_subdev_get_try_crop()

2013-10-31T10:10:10+00:00

The helper function is defined by a macro that is erroneously called
with the compose rectangle instead of the crop rectangle. Fix it.

[media] V4L2: add a common V4L2 subdevice platform data type

2013-10-31T06:30:12+00:00

This struct shall be used by subdevice drivers to pass per-subdevice data,
e.g. power supplies, to generic V4L2 methods, at the same time allowing
optional host-specific extensions via the host_priv pointer. To avoid
having to pass two pointers to those methods, add a pointer to this new
struct to struct v4l2_subdev.

[media] V4L2: (cosmetic) remove redundant use of unlikely()

2013-10-31T06:28:32+00:00

BUG*() and WARN*() macros specify their conditions as unlikely, using
BUG_ON(unlikely(condition)) is redundant, remove it.

[media] V4L: Merge struct v4l2_async_subdev_list with struct v4l2_subdev

2013-07-30T18:54:56+00:00

By integrating the v4l2-async API internals a bit more with
the core overall the v4l2-async code becomes a bit simpler
and easier to follow.

[media] V4L2: support asynchronous subdevice registration

2013-06-21T19:30:00+00:00

Currently bridge device drivers register devices for all subdevices
synchronously, typically, during their probing. E.g. if an I2C CMOS sensor
is attached to a video bridge device, the bridge driver will create an I2C
device and wait for the respective I2C driver to probe. This makes linking
of devices straight forward, but this approach cannot be used with
intrinsically asynchronous and unordered device registration systems like
the Flattened Device Tree. To support such systems this patch adds an
asynchronous subdevice registration framework to V4L2. To use it respective
(e.g. I2C) subdevice drivers must register themselves with the framework.
A bridge driver on the other hand must register notification callbacks,
that will be called upon various related events.

[media] V4L2: add a device pointer to struct v4l2_subdev

2013-06-21T19:28:36+00:00

It is often useful to have simple means to get from a subdevice to the
underlying physical device. This patch adds such a pointer to struct
v4l2_subdev and sets it accordingly in the I2C and SPI cases.
