- add device_caps support - fix bus_info - fix numerous tuner-related problems due to incorrect tests and setting v4l2_tuner fields to wrong values. - remove (audio) input support from the radio: it doesn't belong there. This also fixed a nasty issue where opening the radio would set dev->input to 5 for no good reason. This was never set back to a valid TV input after closing the radio device, thus leaving it at 5 which is out of bounds of the vinput card array. Signed-off-by:

Convert the meye driver to the control framework. Some private controls have been replaced with standardized controls (SHARPNESS and JPEGQUAL). The AGC control looks like it can be replaced by the AUTOGAIN control, but it isn't a boolean so I do not know how to interpret it. The FRAMERATE control looks like it can be replaced by S_PARM, but again, without knowing how to interpret it I decided to leave it alone. Signed-off-by:

If you only poll for events, then vb2_poll will return POLLPRI | POLLERR if no streaming is in progress. That's not right, it's perfectly valid to poll just for events.

When the control IDs were split off from videodev2.h to v4l2-controls.h these new Digital Video controls were forgotten (the two patches may have crossed one another). Move these controls to their proper place in v4l2-controls.h. Signed-off-by:

Newer Exynos4 SoC are equipped with a local camera ISP that controls external raw image sensor directly. Such sensors can be connected through FIMC-LITEn (and MIPI-CSISn) IPs to the ISP, which then feeds image data to the FIMCn IP. Thus there can be two busses associated with an image source (sensor). Rename struct s5p_fimc_isp_info describing external image sensor (video decoder) to struct fimc_source_info to avoid confusion. bus_type is split into fimc_bus_type and sensor_bus_type. The bus type enumeration is extended to include both FIMC Writeback input types. The bus_type enumeration and the data structure name in the board files are modified according to the above changes.

The previous method of registering platform entities into the main driver using driver_find() and then iterating over devices bound to a driver was racy and is being removed here. Nothing was preventing module from unloading during a call to try_module_get(driver->owner). Instead, we look up a device first and then check for its driver while holding device lock. The platform sub-devices are looked up and registered to the top level driver. When any sub-device is not yet initialized and ready the main driver's probe() will be deferred. Signed-off-by:

This patch fixes regression introduced in commit 6319d6a002beb26631 '[media] fimc-lite: Add ISP FIFO output support'. In case of a configuration where video is captured at the video node exposed by the FIMC-LITE driver there is a following video pipeline: sensor -> MIPI-CSIS.n -> FIMC-LITE.n subdev -> FIMC-LITE.n video node In this situation s_stream() handler of the FIMC-LITE.n is called back from within VIDIOC_STREAMON/OFF ioctl of the FIMC-LITE.n video node, through vb2_stream_on/off(), start/stop_streaming and fimc_pipeline_call(set_stream). The fimc->lock mutex is already held then, before invoking vidioc_streamon/off. So it must not be taken again in the s_stream() callback in this case, to avoid a deadlock. This patch makes fimc->out_path atomic_t so the mutex don't need to be taken in the FIMC-LITE subdev s_stream() callback in the DMA output case. Signed-off-by:

Add driver for S5C73M3 image sensor. The driver exposes the sensor as two subdevs: pure sensor and output interface. Two subdev architecture supports interleaved UYVY/JPEG image format with separate frame size for both sub-formats, there is a spearate pad for each sub-format. Signed-off-by:

Modified the G2D driver (which initially supported only H/W Rev.3) to support H/W Rev.4.1 present on Exynos4x12 and Exynos52x0 SOCs. - Set the SRC and DST type to 'memory' instead of using reset values. - FIMG2D v4.1 H/W uses different logic for stretching(scaling). - Use CACHECTL_REG only with FIMG2D v3.
