I prefer if you do them on separate patches, to save my work of not needing to review the entire series again. The ones still pending on my quilt tree are: 0030-v4l-subdev-Generic-ioctl-support.patch 0040-omap3isp-OMAP3-ISP-core.patch 0041-omap3isp-Video-devices-and-buffers-queue.patch 0042-omap3isp-CCP2-CSI2-receivers.patch 0043-omap3isp-CCDC-preview-engine-and-resizer.patch 0044-omap3isp-Statistics.patch 0045-omap3isp-Kconfig-and-Makefile.patch 0046-omap3isp-Add-set-performance-callback-in-isp-platfor.patch with the following diffstat: Documentation/video4linux/v4l2-framework.txt | 5 + MAINTAINERS | 6 + drivers/media/video/Kconfig | 13 + drivers/media/video/Makefile | 2 + drivers/media/video/omap3-isp/Makefile | 13 + drivers/media/video/omap3-isp/cfa_coef_table.h | 61 + drivers/media/video/omap3-isp/gamma_table.h | 90 + drivers/media/video/omap3-isp/isp.c | 2220 +++++++++++++++++++ drivers/media/video/omap3-isp/isp.h | 428 ++++ drivers/media/video/omap3-isp/ispccdc.c | 2268 ++++++++++++++++++++ drivers/media/video/omap3-isp/ispccdc.h | 219 ++ drivers/media/video/omap3-isp/ispccp2.c | 1173 ++++++++++ drivers/media/video/omap3-isp/ispccp2.h | 98 + drivers/media/video/omap3-isp/ispcsi2.c | 1317 ++++++++++++ drivers/media/video/omap3-isp/ispcsi2.h | 166 ++ drivers/media/video/omap3-isp/ispcsiphy.c | 247 +++ drivers/media/video/omap3-isp/ispcsiphy.h | 74 + drivers/media/video/omap3-isp/isph3a.h | 117 + drivers/media/video/omap3-isp/isph3a_aewb.c | 374 ++++ drivers/media/video/omap3-isp/isph3a_af.c | 429 ++++ drivers/media/video/omap3-isp/isphist.c | 520 +++++ drivers/media/video/omap3-isp/isphist.h | 40 + drivers/media/video/omap3-isp/isppreview.c | 2113 ++++++++++++++++++ drivers/media/video/omap3-isp/isppreview.h | 214 ++ drivers/media/video/omap3-isp/ispqueue.c | 1153 ++++++++++ drivers/media/video/omap3-isp/ispqueue.h | 187 ++ drivers/media/video/omap3-isp/ispreg.h | 1589 ++++++++++++++ drivers/media/video/omap3-isp/ispresizer.c | 1693 +++++++++++++++ drivers/media/video/omap3-isp/ispresizer.h | 147 ++ drivers/media/video/omap3-isp/ispstat.c | 1092 ++++++++++ drivers/media/video/omap3-isp/ispstat.h | 169 ++ drivers/media/video/omap3-isp/ispvideo.c | 1255 +++++++++++ drivers/media/video/omap3-isp/ispvideo.h | 202 ++ drivers/media/video/omap3-isp/luma_enhance_table.h | 42 + drivers/media/video/omap3-isp/noise_filter_table.h | 30 + drivers/media/video/v4l2-subdev.c | 2 +- drivers/media/video/videobuf-dma-contig.c | 2 +- include/linux/Kbuild | 1 + 38 files changed, 19769 insertions(+), 2 deletions(-) I used quilt for all patches, except for the one patch with some gifs, where I did a git cherry-pick. So, the imported patches should be ok. Of course, it doesn't hurt do double check. The main issue with the omap3isp is due to the presence of private ioctl's that I don't have a clear idea about what they are really doing. I couldn't see any documentation about them on a very quick look. While I suspect that they are used only for 3A, I have no means of being sure about that. Also, as I've said several times, while I don't like, I have nothing against having some ioctls that would be used by a vendor to implement their own 3A software algorithms that he may need to hide for some reason or have any patents applied to the algorithm, but only if: 1) such algorithms are implemented on userspace; 2) the userspace API used by them is fully documented, in order to allow that someone else with enough motivation and spare time may want to implement his own algorithm (including an open-source one); 3) there are no patents denying or charging for the usage and/or distribution/redistribution of the Kernel with the provided kernel driver; 4) if the device works with a reasonable quality without them (by reasonable I mean like a cheap webcam, where libv4l could use his set of 3A algorithms to provide a good quality). Assuming that all those private ioctl's are really for 3A, it is ok for me to accept such ioctls after being sure that the above applies. I'm not sure how to check (4), as, while I have 2 omap boards here (a Beagleboard and a gumstix), none of them have any sensor.
