Thease are the RFC patches for the DM365 video capture, of which the current set includes only CCDC and the VPFE framework. Once the present set is reviewed, I will send out the other parts like H3A, sensor additions etc. Introduction ------------ This is the proposal of the initial version of design and implementation of the Davinci family (dm644x,dm355,dm365)VPFE (Video Port Front End) drivers using Media Controloler , the initial version which supports the following: 1) dm365 vpfe 2) ccdc,previewer,resizer,h3a,af blocks 3) supports both continuous and single-shot modes 4) supports user pointer exchange and memory mapped modes for buffer allocation This driver bases its design on Laurent Pinchart's Media Controller Design whose patches for Media Controller and subdev enhancements form the base. The driver also takes copious elements taken from Laurent Pinchart and others' OMAP ISP driver based on Media Controller. So thank you all the people who are responsible for the Media Controller and the OMAP ISP driver. Also, the core functionality of the driver comes from the arago vpfe capture driver of which the CCDC capture was based on V4L2, with other drivers like Previwer, and Resizer. The current driver caters to dm6446,dm355 and dm365 of which the current implementation works for dm365. The three VPFE IPs have some common elements in terms of some highe level functionality but there are differences in terms of register definitions and some core blocks. The individual specifications for each of these can be found here: dm6446 vpfe: http://www.ti.com/litv/pdf/sprue38h dm355 vpfe: http://www.ti.com/litv/pdf/spruf71a dm365 vpfe: http://www.ti.com/litv/pdf/sprufg8c The initial version of the driver implementation can be found here: http://git.linuxtv.org/mhadli/v4l-dvb-davinci_devices.git?a=shortlog;h=refs/heads/mc_release Driver Design: Main entities ---------------------------- The hardware modules for dm355,dm365 are mainly ipipe, ipipeif,isif. These hardware modules are generically exposed to the user level in the for of dm6446 style modules. Mainly - ccdc, previewer, resizer in addition to the other histogram and auto color/white balance correction and auto focus modules. 1)MT9P031 sensor module for RAW capture 2)TVP7002 decoder module for HD inputs 3)TVP514x decoder module for SD inputs 4)CCDC capture module 5)Previewer Module for Bayer to YUV conversion 6)Resizer Module for scaling Connection for on-the-fly capture --------------------------------- Mt9P031 ------>CCDC--->Previewer(optional)--->Resizer(optional)--->Video | TVP7002 --- | TV514x --- Manjunath Hadli (3): davinci: vpfe: add dm3xx IPIPEIF hardware support module davinci: vpfe: add support for CCDC hardware for dm365 davinci: vpfe: build infrastructure for dm365 Nagabhushana Netagunte (5): davinci: vpfe: add IPIPE hardware layer support davinci: vpfe: add IPIPE support for media controller driver davinci: vpfe: add ccdc driver with media controller interface davinci: vpfe: add v4l2 video driver support davinci: vpfe: v4l2 capture driver with media interface drivers/media/video/davinci/Kconfig | 46 +- drivers/media/video/davinci/Makefile | 17 +- drivers/media/video/davinci/ccdc_hw_device.h | 6 +- drivers/media/video/davinci/dm365_ccdc.c | 1517 +++++++++ drivers/media/video/davinci/dm365_ccdc_regs.h | 309 ++ drivers/media/video/davinci/dm365_def_para.c | 485 +++ drivers/media/video/davinci/dm365_def_para.h | 39 + drivers/media/video/davinci/dm365_ipipe.c | 4086 +++++++++++++++++++++++++ drivers/media/video/davinci/dm365_ipipe_hw.c | 1012 ++++++ drivers/media/video/davinci/dm365_ipipe_hw.h | 539 ++++ drivers/media/video/davinci/dm3xx_ipipeif.c | 368 +++ drivers/media/video/davinci/vpfe_capture.c | 793 +++++ drivers/media/video/davinci/vpfe_ccdc.c | 813 +++++ drivers/media/video/davinci/vpfe_video.c | 1712 +++++++++++ include/media/davinci/dm365_ccdc.h | 722 +++++ include/media/davinci/dm365_ipipe.h | 1353 ++++++++ include/media/davinci/dm3xx_ipipeif.h | 292 ++ include/media/davinci/imp_common.h | 231 ++ include/media/davinci/imp_hw_if.h | 177 ++ include/media/davinci/vpfe_capture.h | 158 + include/media/davinci/vpfe_ccdc.h | 89 + include/media/davinci/vpfe_types.h | 50 +- include/media/davinci/vpfe_video.h | 142 + 23 files changed, 14914 insertions(+), 42 deletions(-) create mode 100644 drivers/media/video/davinci/dm365_ccdc.c create mode 100644 drivers/media/video/davinci/dm365_ccdc_regs.h create mode 100644 drivers/media/video/davinci/dm365_def_para.c create mode 100644 drivers/media/video/davinci/dm365_def_para.h create mode 100644 drivers/media/video/davinci/dm365_ipipe.c create mode 100644 drivers/media/video/davinci/dm365_ipipe_hw.c create mode 100644 drivers/media/video/davinci/dm365_ipipe_hw.h create mode 100644 drivers/media/video/davinci/dm3xx_ipipeif.c create mode 100644 drivers/media/video/davinci/vpfe_capture.c create mode 100644 drivers/media/video/davinci/vpfe_ccdc.c create mode 100644 drivers/media/video/davinci/vpfe_video.c create mode 100644 include/media/davinci/dm365_ccdc.h create mode 100644 include/media/davinci/dm365_ipipe.h create mode 100644 include/media/davinci/dm3xx_ipipeif.h create mode 100644 include/media/davinci/imp_common.h create mode 100644 include/media/davinci/imp_hw_if.h create mode 100644 include/media/davinci/vpfe_capture.h create mode 100644 include/media/davinci/vpfe_ccdc.h create mode 100644 include/media/davinci/vpfe_video.h -- 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
