[PATCH v5 00/17] Move HEVC stateless controls out of staging

[Benjamin Gaignard]

This series aims to make HEVC uapi stable and usable for hardware
decoder. HEVC uapi is used by 2 mainlined drivers (Cedrus and Hantro)
and 2 out of the tree drivers (rkvdec and RPI).

version 5:
- Change __u16 pic_order_cnt[2] into __s32 pic_order_cnt_val in
  hevc_dpb_entry structure
- Add defines for SEI pic_struct values (patch 4)
- Fix numbers of bits computation in cedrus_h265_skip_bits() parameters
- Fix num_short_term_ref_pic_sets and num_long_term_ref_pics_sps
  documentation (patch 8)
- Rebased on v5-18-rc1

GStreamer H265 decoder plugin aligned with HEVC uAPI v5:

Version 4:
- Add num_entry_point_offsets field in  struct v4l2_ctrl_hevc_slice_params
- Fix V4L2_CID_STATELESS_HEVC_ENTRY_POINT_OFFSETS name
- Initialize control V4L2_CID_STATELESS_HEVC_ENTRY_POINT_OFFSETS
- Fix space/tab issue in kernel-doc
- Add patch to change data_bit_offset definition
- Fix hantro-media SPDX license
- put controls under stateless section in v4l2-ctrls-defs.c

At the end fluster tests results on IMX8MQ is 77/147 for HEVC codec.
