+ * CCDC hardware module for DM355
+ * ------------------------------
+ *
+ * This module is for configuring DM355 CCD controller of VPFE to capture
+ * Raw yuv or Bayer RGB data from a decoder. CCDC has several modules
+ * such as Defect Pixel Correction, Color Space Conversion etc to
+ * pre-process the Bayer RGB data, before writing it to SDRAM. This
+ * module also allows application to configure individual
+ * module parameters through VPFE_CMD_S_CCDC_RAW_PARAMS IOCTL.
+ * To do so, application include dm355_ccdc.h and vpfe_capture.h header
+ * files. The setparams() API is called by vpfe_capture driver
+ * to configure module parameters
+ *
+ * TODO: 1) Raw bayer parameter settings and bayer capture
+ * 2) Split module parameter structure to module specific ioctl structs
+ * 3) add support for lense shading correction
+ * 4) investigate if enum used for user space type definition
+ * to be replaced by #defines or integer

+ * CCDC hardware module for DM6446
+ * ------------------------------
+ *
+ * This module is for configuring CCD controller of DM6446 VPFE to capture
+ * Raw yuv or Bayer RGB data from a decoder. CCDC has several modules
+ * such as Defect Pixel Correction, Color Space Conversion etc to
+ * pre-process the Raw Bayer RGB data, before writing it to SDRAM. This
+ * module also allows application to configure individual
+ * module parameters through VPFE_CMD_S_CCDC_RAW_PARAMS IOCTL.
+ * To do so, application includes dm644x_ccdc.h and vpfe_capture.h header
+ * files. The setparams() API is called by vpfe_capture driver
+ * to configure module parameters. This file is named DM644x so that other
+ * variants such DM6443 may be supported using the same module.
+ *
+ * TODO: Test Raw bayer parameter settings and bayer capture
+ * Split module parameter structure to module specific ioctl structs
+ * investigate if enum used for user space type definition
+ * to be replaced by #defines or integer

+ *
+ * Driver name : VPFE Capture driver
+ * VPFE Capture driver allows applications to capture and stream video
+ * frames on DaVinci SoCs (DM6446, DM355 etc) from a YUV source such as
+ * TVP5146 or Raw Bayer RGB image data from an image sensor
+ * such as Microns' MT9T001, MT9T031 etc.
+ *
+ * These SoCs have, in common, a Video Processing Subsystem (VPSS) that
+ * consists of a Video Processing Front End (VPFE) for capturing
+ * video/raw image data and Video Processing Back End (VPBE) for displaying
+ * YUV data through an in-built analog encoder or Digital LCD port. This
+ * driver is for capture through VPFE. A typical EVM using these SoCs have
+ * following high level configuration.
+ *
+ *
+ * decoder(TVP5146/ YUV/
+ * MT9T001) --> Raw Bayer RGB ---> MUX -> VPFE (CCDC/ISIF)
+ * data input | |
+ * V |
+ * SDRAM |
+ * V
+ * Image Processor
+ * |
+ * V
+ * SDRAM
+ * The data flow happens from a decoder connected to the VPFE over a
+ * YUV embedded (BT.656/BT.1120) or separate sync or raw bayer rgb interface
+ * and to the input of VPFE through an optional MUX (if more inputs are
+ * to be interfaced on the EVM). The input data is first passed through
+ * CCDC (CCD Controller, a.k.a Image Sensor Interface, ISIF). The CCDC
+ * does very little or no processing on YUV data and does pre-process Raw
+ * Bayer RGB data through modules such as Defect Pixel Correction (DFC)
+ * Color Space Conversion (CSC), data gain/offset etc. After this, data
+ * can be written to SDRAM or can be connected to the image processing
+ * block such as IPIPE (on DM355 only).
+ *
+ * Features supported
+ * - MMAP IO
+ * - Capture using TVP5146 over BT.656
+ * - support for interfacing decoders using sub device model
+ * - Work with DM355 or DM6446 CCDC to do Raw Bayer RGB/YUV
+ * data capture to SDRAM.
+ * TODO list
+ * - Support multiple REQBUF after open
+ * - Support for de-allocating buffers through REQBUF
+ * - Support for Raw Bayer RGB capture
+ * - Support for chaining Image Processor
+ * - Support for static allocation of buffers
+ * - Support for USERPTR IO
+ * - Support for STREAMON before QBUF
+ * - Support for control ioctls
