Changeset ab6343956f9c ("[media] V4L2: Add documentation for SDI timings and related flags") added documentation for new V4L2 defines, but it forgot to update videodev2.h.rst.exceptions to point to where the documentation for those new values will be inside the book, causing those warnings: Documentation/output/videodev2.h.rst:6: WARNING: undefined label: v4l2-dv-bt-std-sdi (if the link has no caption the label must precede a section header) Documentation/output/videodev2.h.rst:6: WARNING: undefined label: v4l2-dv-fl-first-field-extra-line (if the link has no caption the label must precede a section header) Documentation/output/videodev2.h.rst:6: WARNING: undefined label: v4l2-in-st-no-v-lock (if the link has no caption the label must precede a section header) Documentation/output/videodev2.h.rst:6: WARNING: undefined label: v4l2-in-st-no-std-lock (if the link has no caption the label must precede a section header) Fixes: ab6343956f9c ("[media] V4L2: Add documentation for SDI timings and related flags") Cc: Charles-Antoine Couret <charles-antoine.couret@nexvision.fr> Cc: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

2016-09-09[media] v4l: rcar-fcp: Don't force users to check for disabled FCP supportLaurent Pinchart
The rcar_fcp_enable() function immediately returns successfully when the FCP device pointer is NULL to avoid forcing the users to check the FCP device manually before every call. However, the stub version of the function used when the FCP driver is disabled returns -ENOSYS unconditionally, resulting in a different API contract for the two versions of the function. As a user that requires FCP support will fail at probe time when calling rcar_fcp_get() if the FCP driver is disabled, the stub version of the rcar_fcp_enable() function will only be called with a NULL FCP device. We can thus return 0 unconditionally to align the behaviour with the normal version of the function.

2016-09-09[media] media: platform: pxa_camera: make a standalone v4l2 deviceRobert Jarzmik
This patch removes the soc_camera API dependency from pxa_camera. In the current status : - all previously captures are working the same on pxa270 - the s_crop() call was removed, judged not working (see what happens soc_camera_s_crop() when get_crop() == NULL) - if the pixel clock is provided by then sensor, ie. not MCLK, the dual stage change is not handled yet. => there is no in-tree user of this, so I'll let it that way - the MCLK is not yet finished, it's as in the legacy way, ie. activated at video device opening and closed at video device closing. In a subsequence patch pxa_camera_mclk_ops should be used, and platform data MCLK ignored. It will be the sensor's duty to request the clock and enable it, which will end in pxa_camera_mclk_ops.
