[media] v4l2: added missing mutex.h include to v4l2-ctrls.h

2013-07-26T13:14:52Z

This patch fixes following error: include/media/v4l2-ctrls.h:193:15: error: field ‘_lock’ has incomplete type include/media/v4l2-ctrls.h: In function ‘v4l2_ctrl_lock’: include/media/v4l2-ctrls.h:570:2: error: implicit declaration of function ‘mutex_lock’ [-Werror=implicit-function-declaration] include/media/v4l2-ctrls.h: In function ‘v4l2_ctrl_unlock’: include/media/v4l2-ctrls.h:579:2: error: implicit declaration of function ‘mutex_unlock’ [-Werror=implicit-function-declaration] Signed-off-by: Andrzej Hajda Signed-off-by: Kyungmin Park Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] exynos4-is: Correct colorspace handling at FIMC-LITE

2013-06-28T18:33:27Z

Ensure the colorspace is properly adjusted by the driver for YUV and Bayer image formats. The subdev try_fmt helper is simplified. Signed-off-by: Sylwester Nawrocki Signed-off-by: Kyungmin Park Signed-off-by: Mauro Carvalho Chehab

[media] V4L2: soc-camera: fix uninitialised use compiler warning

2013-06-28T17:57:18Z

In scan_async_group() if the size parameter is negative, the sasd pointer will be used uninitialised: drivers/media/platform/soc_camera/soc_camera.c: In function "soc_camera_host_register": drivers/media/platform/soc_camera/soc_camera.c:1514:55: warning: "sasd" may be used uninitialized in this function [-Wmaybe-uninitialized] sasd->asd.match.i2c.adapter_id, sasd->asd.match.i2c.address); ^ drivers/media/platform/soc_camera/soc_camera.c:1464:34: note: "sasd" was declared here struct soc_camera_async_subdev *sasd; Fix this by making "size" and the array, from which it is assigned unsigned.

[media] sh_mobile_ceu_camera: add asynchronous subdevice probing support

2013-06-21T19:35:53Z

Use the v4l2-async API to support asynchronous subdevice probing, including the CSI2 subdevice. Synchronous probing is still supported too. Signed-off-by: Guennadi Liakhovetski Acked-by: Hans Verkuil Acked-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

[media] soc-camera: add V4L2-async support

2013-06-21T19:34:17Z

Add support for asynchronous subdevice probing, using the v4l2-async API. The legacy synchronous mode is still supported too, which allows to gradually update drivers and platforms. The selected approach adds a notifier for each struct soc_camera_device instance, i.e. for each video device node, even when there are multiple such instances registered with a single soc-camera host simultaneously.

[media] soc-camera: switch I2C subdevice drivers to use v4l2-clk

2013-06-21T19:32:36Z

Instead of centrally enabling and disabling subdevice master clocks in soc-camera core, let subdevice drivers do that themselves, using the V4L2 clock API and soc-camera convenience wrappers.

[media] V4L2: support asynchronous subdevice registration

2013-06-21T19:30:00Z

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

2013-06-21T19:28:36Z

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.

[media] V4L2: add temporary clock helpers

2013-06-21T19:28:02Z

Typical video devices like camera sensors require an external clock source. Many such devices cannot even access their hardware registers without a running clock. These clock sources should be controlled by their consumers. This should be performed, using the generic clock framework. Unfortunately so far only very few systems have been ported to that framework. This patch adds a set of temporary helpers, mimicking the generic clock API, to V4L2. Platforms, adopting the clock API, should switch to using it. Eventually this temporary API should be removed.

[media] soc-camera: add host clock callbacks to start and stop the master clock

2013-06-21T18:35:51Z

Currently soc-camera uses a single camera host callback to activate the interface master clock and to configure the interface for a specific client. However, during probing we might not have the information about a client, we just need to activate the clock. Add new camera host driver callbacks to only start and stop the clock without and client-specific configuration.
