My main concern is that cafe_ccic driver structure and application usage is much simple and have no DMA chain while SOC CCIC should support soc_camera/DMA chain/user pointer. So it will take much effort to share DVP settings, such as image size and HSYNC_PO/VSYNC_PO, etc. Is there any existing drivers with such similar abstraction for decision making reference?
