+ * 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/DM365 only).
+ *
+ * Features supported
+ * - MMAP IO
+ * - USERPTR IO
+ * - Capture using TVP5146 over BT.656
+ * - Support for interfacing decoders using sub device model
+ * - Work with DM365 or DM355 or DM6446 CCDC to do Raw Bayer
+ * RGB/YUV data capture to SDRAM.
