Add support to uvc driver for NOMMU arch including add function uvc_queue_get_unmapped_area() and make some changes in uvc_queue_mmap(). So that uvc camera can be used on nommu arch like blackfin. Signed-off-by:

This camera driver supports only rising edge, which is the default setting of the device. The function mt9m111_setup_pixfmt() overwrites this setting. So the driver actually uses falling edge. This patch corrects that. Signed-off-by:

The setup of the pixel clock is done wrong in the mt9v022 driver. The 'Invert Pixel Clock' bit has to be set to 1 for falling edge and not for rising. This is not clearly described in the data sheet. Tested on pcm037 and pcm027/pcm990. Signed-off-by:

soc_mbus_get_fmtdesc() returning NULL means only, that no standard mediabus code -> fourcc conversion is known, this shouldn't be treated as an error by drivers. Signed-off-by:

12-bit formats, similar to YUV 4:2:0 occupy 3 bytes for each two pixels and cannot be described by any of the existing SOC_MBUS_PACKING_* macros. This patch adds a new one SOC_MBUS_PACKING_1_5X8 to describe such formats and extends soc_mbus_samples_per_pixel() to support it. Signed-off-by:

Since V4L2_MBUS_FMT_* codes have become large and sparse, they cannot be used as array indices anymore. Signed-off-by:
-
Guennadi Liakhovetski authored
Recently mediabus pixel format codes have become a part of the user- space API, at which time their values also have been changed from contiguous numbers, running from 0 to sparse numbers with values around 0x1000, 0x2000, 0x3000... This made them unsuitable for the use as array indices. This patch switches soc-camera internal format look-ups to not depend on values of those macros. Signed-off-by:

Add an soc-camera host livecrop operation to implement live zoom. If a host driver implements it, it should take care to preserve output frame format, then live crop doesn't break streaming. Signed-off-by:

s5p-fimc now also implements a camera capture video node so move it under the "Video capture devices" Kconfig menu. Also update the entry to reflect the driver's coverage of EXYNOS4 SoCs and separate the Makefile entry from the soc-camera drivers set. Signed-off-by:

Use the expression "video stream" instead of "color camera" which is more correct as the driver supports the RGB and IR image on the same endpoint. Signed-off-by:

Move large communications buffers out of stack and into device structure. This prevents the frame size from being >1kB and fixes a compiler warning when CONFIG_FRAME_WARN=1024: drivers/media/video/gspca/kinect.c: In function ‘send_cmd.clone.0’: drivers/media/video/gspca/kinect.c:202: warning: the frame size of 1548 bytes is larger than 1024 bytes Reported-by:

This adds detailed documentation about the driver's extension unit control features. Part of it has been adopted from the dynctrl.txt that used to be available in the driver's previous Subversion repository. The documentation has been rewritten to match the current implementation, in particular to capture the new XU control support including UVCIOC_CTRL_QUERY. Signed-off-by:

Martin Rubli authored
This ioctl extends UVCIOC_CTRL_GET/SET by not only allowing to get/set XU controls but to also send arbitrary UVC commands to XU controls, namely GET_CUR, SET_CUR, GET_MIN, GET_MAX, GET_RES, GET_LEN, GET_INFO and GET_DEF. This is required for applications to work with XU controls, so that they can properly query the size and allocate the necessary buffers. Signed-off-by:
