Yeah, though the for-loop iterates over 4*7 entry values, so stays below the RKISP1_CIF_ISP_HISTOGRAM_WEIGHT_GRIDS_SIZE_V10 in all cases. > Actually the real number of weight values are 25 (5x5) for rk3399, > the last 3 are not used.

If you look at my V12-patch [0] the weight handling is done different there and from the registers, it looks like they exchanges that part of the isp.

I've changed this like your suggestions and will give a bit of time for the stuff above. But I guess I can send a v5 some time tomorrow? Thanks for your input Heiko
