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 V4L2_SEL_TGT_CROP_BOUNDS, V4L2_SEL_TGT_COMPOSE_BOUNDS selection targets are not supposed to be handled in the set_selection ioctl. Remove the code that doesn't do anything sensible now and make sure ctx->state is modified with the spinlock held. Signed-off-by:

clk_set_rate(), clk_enable() functions can fail, so check the return values to avoid surprises. While at it use ERR_PTR() value to indicate an invalid clock. Signed-off-by:

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.

Make sure bytesperline for Cb, Cr planes for V4L2_PIX_FMT_YUV420M format is half of the Y plane value, rather than having same bytesperline for all planes. While at it, simplify the bytesperline parameter handling by storing it when image format is set and returning those values when getting the format, instead of recalculating bytesperline from intermediate parameters.

Fixes a v4l2-compliance error: setting audmode to a value other than mono or stereo for a radio device should map to MODE_STEREO. The spec specifies that for radio devices only mono and stereo audmodes are valid. If the user specifies another audmode in v4l2_tuner, then that should be mapped to valid audmode. That didn't happen here. Note that tuner drivers might decide to limit the possible audmode even further if it only supports mono. In that case the tuner driver can set audmode to mono. However, that new value wasn't copied back to t->audmode, and that has been fixed as well in this patch. Signed-off-by:

This patch adds V4L2 sub-device driver for OV9650/OV9652 image sensors. The driver exposes following V4L2 controls: - auto/manual exposure, - auto/manual white balance, - auto/manual gain, - brightness, saturation, sharpness, - horizontal/vertical flip, - color bar test pattern, - banding filter (power line frequency). Frame rate can be configured with g/s_frame_interval pad level ops. Supported resolution are only: SXGA, VGA, QVGA. Signed-off-by:

This patch adds a helper function that allows to modify range, i.e. minimum, maximum, step and default value of a v4l2 control, after the control has been created and initialized. This is helpful in situations when range of a control depends on user configurable parameters, e.g. camera sensor absolute exposure time depending on an output image resolution and frame rate. v4l2_ctrl_modify_range() function allows to modify range of an INTEGER, BOOL, MENU, INTEGER_MENU and BITMASK type controls.
