From: Muralidharan Karicheri <a0868495@xxxxxxxxxxxxxxxxxxxxxxxxxx> VPFE Capture driver for DaVinci Media SOCs :- DM355 and DM6446 These patches add support for VPFE (Video Processing Front End) based video capture on DM355 and DM6446 EVMs. For more details on the hardware configuration and capabilities, please refer the vpfe_capture.c header. This patch set consists of following:- Patch 1: VPFE Capture bridge driver Patch 2: CCDC hw device header file Patch 3: DM355 CCDC hw module Patch 4: DM644x CCDC hw module Patch 5: common types used across CCDC modules Patch 6: Makefile and config files for the driver Patch 7: DM355 platform and board setup Patch 8: DM644x platform and board setup Patch 9: Remove outdated driver files from davinci git tree The initial version of this driver was reviewed by reviewers mentioned below. Following are the Major comments incorporated into the driver based on this :- 1) Restructure the files into following:- vpfe_capture.[ch] - bridge driver ccdc_types.h - types used across ccdc modules vpfe_types.h - types used across vpfe specific drivers dm644x_ccdc.[ch] - ccdc module for DM644x dm644x_ccdc_regs.h - register defines for DM644x dm355_ccdc.[ch] - ccdc module for DM355 dm355_ccdc_regs.h - register defines for DM644x 2) Simplify data structures for vpfe capture driver (avoid structure based on multiple channels) 3) Cleanup device registration and initialization 4) Video buffer handling issues In addition to this, the driver is ported to the new sub device model. Tested the driver using the tvp5146 decoder (version migrated to sub device model by Vaibhav Hiremath and is being reviewed currently on the list). So this patch depends on the above driver. NOTE: Dependent on the TVP514x decoder driver patch for migrating the driver to sub device model from Vaibhav Hiremath Following tests are performed. 1) Capture and display video (PAL & NTSC) from tvp5146 decoder. Displayed using fbdev device driver available on davinci git tree 2) Tested with driver built statically and dynamically Muralidhara Karicheri Reviewed By "Hans Verkuil".
