Merge branch 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull second set of media updates from Mauro Carvalho Chehab: "Despite its size, most of the stuff here is trivial. This series contains: - s5p-mfc: additions at the driver and at the core to support H.264 hardware codec; - Some improvements at s5p and davinci embedded drivers; - Some V4L2 compliance fixes applied on a few drivers; - Several random trivial patches, including several fixes and a few new board support additions; Notes: 1) Some Exynos media patches were dependent on some -arm fixes that got merged on changeset 782cd9e. That's why this pull request is based that changeset. 2) As promised, I reviewed the pending VB2 DMABUF series. While setting a test environment, it was noticed that the upstream support for Samsung Exynos 4 boards (smdk310 and Origen) are broken upstream, likely due to regressions: both defconfigs are wrong and regulator settings for both boards are broken. That, allied with some bug at the dummy regulator driver, causes OOPSes during boot time. Long story short: even fixing the above, the proposed patches OOPSed when running the DMABUF test. Not sure yet if the OOPSes are due to some other undetected regressions, or due to some bug on the patches. Due to the above, DMABUF patches for vb2 got NACKed for 3.7." * 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (109 commits) [media] m5mols: Add missing #include <linux/sizes.h> [media] stk1160: Add support for S-Video input Revert "[media] omap3isp: Replace cpu_is_omap3630() with ISP revision check" [media] dvb: LNA implementation changes [media] v4l2-ioctl: fix W=1 warnings [media] v4l2-ioctl: add blocks check for VIDIOC_SUBDEV_G/S_EDID [media] omap3isp: Fix compilation error in ispreg.h [media] rc-msi-digivox-ii: Add full scan keycodes [media] cx25821: testing the wrong variable [media] tda18271-common: hold the I2C adapter during write transfers [media] ds3000: add module parameter to force firmware upload [media] drivers/media: Remove unnecessary semicolon [media] winbond: remove space from driver name [media] iguanair: cannot send data from the stack [media] omap3isp: Replace cpu_is_omap3630() with ISP revision check [media] dvb-usb: print small buffers via %*ph [media] uvc: Add return code check at vb2_queue_init() [media] em28xx: Replace memcpy with struct assignment [media] bt8xx: Add video4linux control V4L2_CID_COLOR_KILLER [media] mem2mem_testdev: Use devm_kzalloc() in probe ...

1012 <entry>Two-planar format used by Samsung S5C73MX cameras. The
1013first plane contains interleaved JPEG and UYVY image data, followed by meta data
1014in form of an array of offsets to the UYVY data blocks. The actual pointer array
1015follows immediately the interleaved JPEG/UYVY data, the number of entries in
1016this array equals the height of the UYVY image. Each entry is a 4-byte unsigned
1017integer in big endian order and it's an offset to a single pixel line of the
1018UYVY image. The first plane can start either with JPEG or UYVY data chunk. The
1019size of a single UYVY block equals the UYVY image's width multiplied by 2. The
1020size of a JPEG chunk depends on the image and can vary with each line.
1021<para>The second plane, at an offset of 4084 bytes, contains a 4-byte offset to
1022the pointer array in the first plane. This offset is followed by a 4-byte value
1023indicating size of the pointer array. All numbers in the second plane are also
1024in big endian order. Remaining data in the second plane is undefined. The
1025information in the second plane allows to easily find location of the pointer
1026array, which can be different for each frame. The size of the pointer array is
1027constant for given UYVY image height.</para>
1028<para>In order to extract UYVY and JPEG frames an application can initially set
1029a data pointer to the start of first plane and then add an offset from the first
1030entry of the pointers table. Such a pointer indicates start of an UYVY image
1031pixel line. Whole UYVY line can be copied to a separate buffer. These steps
1032should be repeated for each line, i.e. the number of entries in the pointer
1033array. Anything what's in between the UYVY lines is JPEG data and should be
1034concatenated to form the JPEG stream. </para>
