Subject: [PATCH v3 1/9] media: hevc: Modify structures to follow H265 ITU spec
Date:   Mon, 22 Feb 2021 13:23:58 +0100
Message-Id: <20210222122406.41782-2-benjamin.gaignard@collabora.com>

The H.265 ITU specification (section 7.4) define the general
slice segment header semantics.
Modified/added fields are:
- video_parameter_set_id: (7.4.3.1) identifies the VPS for
reference by other syntax elements.
- seq_parameter_set_id: (7.4.3.2.1) specifies the value of
the vps_video_parameter_set_id of the active VPS.
- chroma_format_idc: (7.4.3.2.1) specifies the chroma sampling
 relative to the luma sampling
- pic_parameter_set_id: (7.4.3.3.1) identifies the PPS for
reference by other syntax elements
- num_ref_idx_l0_default_active_minus1: (7.4.3.3.1) specifies
the inferred value of num_ref_idx_l0_active_minus1
- num_ref_idx_l1_default_active_minus1: (7.4.3.3.1) specifies
the inferred value of num_ref_idx_l1_active_minus1
- slice_segment_addr: (7.4.7.1) specifies the address of
the first coding tree block in the slice segment
- num_entry_point_offsets: (7.4.7.1) specifies the number of
entry_point_offset_minus1[ i ] syntax elements in the slice header

Add HEVC decode params contains the information used in section
"8.3 Slice decoding process" of the specification to let the hardware
perform decoding of a slices.

Adapt Cedrus driver according to these changes.

version 3:
- Add documentation about the new structuers and fields.

version 2:
- remove all change related to scaling
- squash commits to a coherent split
- be more verbose about the added fields
