One more question: does the ISP produce a reasonable picture if it doesn't receive these params? If not (i.e. you always need to provide params), then I think you should provide a default rkisp1_isp_params_cfg struct that can be used as a template for application writers. Perhaps it can be part of the driver as the initial params config. I think even if the ISP does work without params it is still worthwhile doing this. The params are complex and having an example on how to initialize it would be helpful.

The params are not very complex.
