Subject: [PATCH v11 00/17] Move HEVC stateless controls out of staging

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 11:
- Be more verbose about num_entry_point_offsets field usage.
- Fix various typos in "Add documentation to uAPI structure" patch.

version 10:
- Rebased on media_stage/master
- Add Acked-by tag from Nicolas
- Add Tested-by tag from Jernej
- Fix typo in patch 14

This version has been tested with these branches:
- GStreamer: https://gitlab.freedesktop.org/benjamin.gaignard1/gstreamer/-/tree/HEVC_aligned_with_kernel_5.15
- Linux: https://gitlab.collabora.com/benjamin.gaignard/for-upstream/-/tree/HEVC_UAPI_V10

With patches to decode 10-bits bitstream and produce P010 frames the Fluster score 
which was 77/147 before, is now 141/147.
The 10-bits series will comes after this because of it dependency to
uAPI change. If you are curious you can find the WIP branch here:
https://gitlab.collabora.com/benjamin.gaignard/for-upstream/-/commits/WIP_HEVC_UAPI_V10

The 6 failing tests are:
- PICSIZE_{A,B,C,D}_Bossen_1 where resolutions are to big for Hantro hardware.
- WPP_D_ericsson_MAIN_2 and WPP_D_ericsson_MAIN10_2 are visually ok but some 
  difference exist on 5 decoded frames. Some pixels values are no the same 
  the very end of few lines.

version 9:
- Reword some commit message
- Use fls()
- Remove useless padding at the end of hevc structures
- Reword all _minus* field description
- change CVS to codec video sequence
- Fix various typo
- Fix undefined label: v4l2-ctrl-flag-dynamic-array warning
- fix the waring reported by 'scripts/kernel-doc -none
  include/uapi/linux/v4l2-controls.h'

version 8:
- Same than v7 but rebased on media_stage/master

version 7:
- Apply Jernej patches for Cedrus about bit offset definition and
  V4L2_CID_STATELESS_HEVC_SLICE_PARAMS being a dynamic array control.
- Based on media_tree/master

version 6:
- Add short_term_ref_pic_set_size and long_term_ref_pic_set_size
  in v4l2_ctrl_hevc_decode_params structure.
- Change slice_pic_order_cnt type to s32 to match with PoC type.
- Set V4L2_CTRL_FLAG_DYNAMIC_ARRAY flag automatically when using
  V4L2_CID_STATELESS_HEVC_SLICE_PARAMS control.
- Add a define for max slices count
- Stop using Hantro dedicated control.

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

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
