[media] videobuf2: Add support for file access mode flags for DMABUF exporting

2013-12-09T16:50:50Z

Currently it is not possible for userspace to map a DMABUF exported buffer with write permissions. This patch allows to also pass O_RDONLY/O_RDWR when exporting the buffer, so that userspace may map it with write permissions.

[media] v4l: Fix typo in v4l2_subdev_get_try_crop()

2013-10-31T10:10:10Z

The helper function is defined by a macro that is erroneously called with the compose rectangle instead of the crop rectangle. Fix it. Signed-off-by: Laurent Pinchart Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

[media] media: i2c: add driver for dual LED Flash, lm3560

2013-10-31T08:36:39Z

Adds the driver for the LM3560, dual LED Flash The LM3560 has two 1A constant current driver for high current white LEDs. It is controlled via an I2C compatible interface(up to 400kHz). Each flash brightness, torch brightness and enable/disable can be controlled independantly, but flash timeout and operation mode are shared.

[media] V4L2: soc-camera: work around unbalanced calls to .s_power()

2013-10-31T06:38:40Z

Some non soc-camera drivers, e.g. em28xx, use subdevice drivers, originally written for soc-camera, which use soc_camera_power_on() and soc_camera_power_off() helpers to implement their .s_power() methods. Those helpers in turn can enable and disable a clock, if it is supplied to them as a parameter. This works well when camera host drivers balance their calls to subdevices' .s_power() methods. However, some such drivers fail to do that, which leads to unbalanced calls to v4l2_clk_enable() / v4l2_clk_disable(), which then in turn produce kernel warnings. Such behaviour is wrong and should be fixed, however, sometimes it is difficult, because some of those drivers are rather old and use lots of subdevices, which all should be tested after such a fix. To support such drivers this patch adds a work-around, allowing host drivers or platforms to set a flag, in which case soc-camera helpers will only enable the clock, if it is disabled, and disable it only once on the first call to .s_power(0).

[media] V4L2: add a v4l2-clk helper macro to produce an I2C device ID

2013-10-31T06:33:02Z

To obtain a clock reference consumers supply their device object to the V4L2 clock framework. The latter then uses the consumer device name to find a matching clock. For that to work V4L2 clock providers have to provide the same device name, when registering clocks. This patch adds a helper macro to generate a suitable device name for I2C devices.

[media] V4L2: add v4l2-clock helpers to register and unregister a fixed-rate clock

2013-10-31T06:31:30Z

Many bridges and video host controllers supply fixed rate always on clocks to their I2C devices. This patch adds two simple helpers to register and unregister such a clock. Signed-off-by: Guennadi Liakhovetski Signed-off-by: Mauro Carvalho Chehab

[media] soc-camera: switch to using the new struct v4l2_subdev_platform_data

2013-10-31T06:30:56Z

This prepares soc-camera to use struct v4l2_subdev_platform_data for its subdevice-facing API, which would allow subdevice driver re-use. Signed-off-by: Guennadi Liakhovetski Signed-off-by: Mauro Carvalho Chehab

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

2013-10-31T06:30:12Z

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. Signed-off-by: Guennadi Liakhovetski Signed-off-by: Mauro Carvalho Chehab

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