Add support for the ISP's lane shifter. To use the shifter, set different pixel formats at each end of the link at the CCDC input. This has only been tested shifting Y12 and SBGGR12 from a parallel sensor to Y8 and SBGGR8 (respectively) at the CCDC input. Support has also been added for other formats and other shifting values, but is untested. Shifting data coming from one of the serial sensor interfaces (CSI2a, etc) is also untested. As before, ccdc_try_format() does not check that the format at its input is compatible with the format coming from the sensor interface. This consistency check is first done when activating the pipeline. These patches apply to Laurent's media-2.6.38-0001-omap3isp branch, based on 2.6.38 Changes since v3: -applies to media-2.6.38-0001-omap3isp -added missing DocBook changes needed for Y12, e.g. pixfmt-y12.xml -omap3isp_configure_bridge() takes 'unsigned int' instead of 'int' shift -renamed link_has_shifter -> shifter_link Changes since v2: -new formats are also added to Documentation/DocBook/v4l/ -reintroduce .data_lane_shift for sensors whose LSB is not aligned with sensor interfaces's LSB. -style changes according to feedback Changes since v1: -added support for remaining 8-bit Bayer formats (SGBRG8_1X8 & SRGGB8_1X8) -moved omap3isp_is_shiftable() from isp.c to ispvideo.c and return bool -moved 'shift' calculation from omap3isp_configure_bridge() to ccdc_configure() -added 'shift' arg to omap3isp_configure_bridge() -misc minor changes according to feedback (removed unnecessary tests, etc.) Michael Jones (4): v4l: add V4L2_PIX_FMT_Y12 format media: add 8-bit bayer formats and Y12 omap3isp: ccdc: support Y10/12, 8-bit bayer fmts omap3isp: lane shifter support Documentation/DocBook/media-entities.tmpl | 1 + Documentation/DocBook/v4l/pixfmt-y12.xml | 79 +++++++++++++++++++ Documentation/DocBook/v4l/pixfmt.xml | 1 + Documentation/DocBook/v4l/subdev-formats.xml | 59 ++++++++++++++ drivers/media/video/omap3isp/isp.c | 7 +- drivers/media/video/omap3isp/isp.h | 5 +- drivers/media/video/omap3isp/ispccdc.c | 33 +++++++- drivers/media/video/omap3isp/ispvideo.c | 108 ++++++++++++++++++++++---- drivers/media/video/omap3isp/ispvideo.h | 3 + include/linux/v4l2-mediabus.h | 7 +- include/linux/videodev2.h | 1 + 11 files changed, 278 insertions(+), 26 deletions(-) create mode 100644 Documentation/DocBook/v4l/pixfmt-y12.xml -- 1.7.4.2 MATRIX VISION GmbH, Talstrasse 16, DE-71570 Oppenweiler Registergericht: Amtsgericht Stuttgart, HRB 271090 Geschaeftsfuehrer: Gerhard Thullner, Werner Armingeon, Uwe Furtner -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
