[PATCH 2/2] media: iris: add hierarchical coding support for ar50lt encoder
From: Vishnu Reddy
Date: Thu Jul 09 2026 - 22:42:35 EST
From: Gourav Kumar <gouravk@xxxxxxxxxxxxxxxx>
Add LAYER_ENABLE, LAYER_TYPE_H264/HEVC, LAYER_COUNT_H264/HEVC and
per-layer bitrate fw_caps entries to inst_fw_cap_gen2_ar50lt_enc,
enabling V4L2_CID_MPEG_VIDEO_H264_HIERARCHICAL_CODING and related
hierarchical/layered encoding controls for ar50lt platforms.
