* 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
+ * pre-process the Bayer RGB data, before writing it to SDRAM.
*
* TODO: 1) Raw bayer parameter settings and bayer capture
* 2) Split module parameter structure to module specific ioctl structs
