[PATCH v1 08/11] media: uapi: Add NXP NEOISP user interface header file

Antoine Bouyer
2026-04-13T16:04:50Z

Add user space api header file for meta data structures definitions.

This header describes `parameters` buffer for the ISP blocks control by
userspace, and `statistics` buffer for userspace and IPA handling.

These 2 buffers both support legacy and extensible modes. Legacy mode is
a static fixed buffer structure, while extensible mode uses the
v4l2-isp generic definitions to support various amount of ISP blocks.

Parameters buffer uses v4l2-isp generic definitions, so as other ISP
devices (rkisp1, mali-c55). Statistics buffer uses the newly introduced
generic `v4l2_isp_stats_buffer`, which behaves the same as the generic
`v4l2_isp_params_buffer`.
