Subject: [PATCH v6 00/17] media: rkvdec: Add support for VDPU381 and VDPU383
These variants are found respectively in the RK3588 and RK3576 SoCs.
This patch only adds support for H264 and H265 in both variants.
As there is a considerable part of the code that can be shared with the
already supported rkvdec decoder driver, the support for these variants
is added here rather than writing a new driver.
This patch set uses the newly introduced hevc_ext_sps_[ls]t_rps v4l2
controls for HEVC.
Therefore, a patched version of userpace tools is needed for HEVC
support (added for GStreamer[1] and in an early stage for FFmpeg[2]).
The DTS changes can be found in another patch set: [3]

Changes since v5:
- Extract multicore management in separate commit
- Move variant specific functions to an ops struct
- Fix a typo and "h264" -> "hevc" copy/paste mistakes
- Move RKVDEC_*_PIXELS to rkvdec.h
- Drop VDPU383_*_PIXELS, use the the RKVDEC ones instead
- Change RKVDEC_1080P_PIXELS value to 1920 * 1088
- Long and short term ref sets extend controls:
- Add them in visl traces
- Reword documentation to specify SPS extension and use
- Mention Vulkan Video API similarity
- Specify behavior for empty array values
- Reorder struct fields to ensure fixed compiled size
- Remove the mention of V4L2_CTRL_FLAG_DYNAMIC_ARRAY flag
Changes since v4:
- Add basic ext_sps_[ls]t_rps validation (flags only)
- Add missing copyright in new common files
- Rename num_coded_fmts, rcb_num, clk_count
- Avoid allocating RCB config when not needed
- Merge rkvdec_config into rkvdec_variant
- Keep rkvdec_hevc_get_image_fmt per variant
Changes since v3:
- Rebased on latest next (ea299a216426) + HEVC support for rk3399
Changes since v2:
- Rebased on Kwiboo's HEVC support for rk3399
- Include hevc_ext_sps_[ls]t_rps v4l2 controls commits
- Remove empty lines at end of files
- Rename RKVDEC2_ALLOC_* to RKVDEC_ALLOC_*
- Set min_with and min_height to 64
- Remove vdpu38x_fill_pixfmt_mp() function
- Handle userspace not supporting hevc_ext_sps_[ls]t_rps
- Make all config structs static const
Changes since v1:
- Add parsing of the short and long term ref frame sets from the new v4l2
controls
- Add RPS cache to avoid parsing the same data again
- Fix HEVC pixel formats selection
- Fix multiple indentation errors
