14 | * CCDC hardware module for DM355 |
15 | * ------------------------------ | |
16 | * | |
17 | * This module is for configuring DM355 CCD controller of VPFE to capture | |
18 | * Raw yuv or Bayer RGB data from a decoder. CCDC has several modules | |
19 | * such as Defect Pixel Correction, Color Space Conversion etc to | |
b25db383 | 20 | * pre-process the Bayer RGB data, before writing it to SDRAM. |
dd2ceb1a MK |
21 | * |
22 | * TODO: 1) Raw bayer parameter settings and bayer capture | |
23 | * 2) Split module parameter structure to module specific ioctl structs | |
24 | * 3) add support for lense shading correction | |
25 | * 4) investigate if enum used for user space type definition | |
26 | * to be replaced by #defines or integer | |
