From: Shunqian Zheng <zhengsq@rock-chips.com> Add the Rockchip ISP1 specific processing parameter format V4L2_META_FMT_RK_ISP1_PARAMS and metadata format V4L2_META_FMT_RK_ISP1_STAT_3A for 3A.
These formats are not documented in the V4L2 spec. I think it is documented in rkisp1-config.h, so you need to add something to meta-formats.rst. It's OK to refer to that header, as long as it is clear where the documentation of the format can be found. Regards, Hans
