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 v4l2 core helper function that can be used as the log_status handler for subdevs that only need to log state of the v4l2 controls owned by the subdev's control handler. Signed-off-by:

Add a v4l2 core helper function that can be used as the subdev .subscribe_event handler. This allows to eliminate some boilerplate from drivers that are only handling the control events. 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.

This patch fixes a bug which causes all histogram regions to start in the top left corner of the image. The histogram region coordinates are 16 bit values which share a 32 bit register. The bug is due to the region end value assignments overwriting the region start values with zero. Signed-off-by:

The preview engine includes filters that consume columns and lines as part of their operation, thus resulting in a cropped image. To allow turning those filters on/off during streaming without affecting the output image size, the driver adds additional cropping to make the total number of cropped columns and lines constant regardless of which filters are enabled. This process needlessly includes the CFA filter, as whether the filter is enabled only depends on the sink pad format, which can't change during streaming. Exclude the CFA filter from the preview engine margins. Signed-off-by:

Ming Lei reported: IMO, there is a minor fault in the error handling path of uvc_status_start() inside uvc_v4l2_open(), and the 'users' count should have been decreased before usb_autopm_put_interface(). In theory, a [URB resubmission] warning can be triggered when the device is opened just between usb_autopm_put_interface() and atomic_dec(&stream->dev->users). The fix is trivial. Reported-by:

Events for the iMon Knob pad where not correctly interpreted on ARM, resulting in buggy mouse movements (cursor going straight out of the screen), key pad only generating KEY_RIGHT and KEY_DOWN events. A reproducer is: int main(int argc, char ** argv) { char rel_x = 0x00; printf("rel_x:%d @%s:%d\n", rel_x, __FILE__, __LINE__); rel_x = 0x0f; printf("rel_x:%d @%s:%d\n", rel_x, __FILE__, __LINE__); rel_x |= ~0x0f; printf("rel_x:%d @%s:%d\n", rel_x, __FILE__, __LINE__); return 0; } (running on x86 or amd64) $ ./test rel_x:0 @test.c:6 rel_x:15 @test.c:7 rel_x:-1 @test.c:8 (running on armv6) rel_x:0 @test.c:6 rel_x:15 @test.c:7 rel_x:255 @test.c:8 Forcing the rel_x and rel_y variables as signed char fixes the issue.
