Subject: [PATCH v3 00/10] media: rkvdec: Add H.264 High 10 and 4:2:2 profile support

This is a revival of a 3 year old series [1] now that NV15/NV20/NV30 support
for display driver have landed in drm-misc tree.

This series adds H.264 High 10 and 4:2:2 profile support to the Rockchip
Video Decoder driver.

Patch 1 adds helpers for calculating plane bytesperline and sizeimage.
Patch 2 adds two new pixelformats for semi-planer 10-bit 4:2:0/4:2:2 YUV.

Patch 3 change to use bytesperline and buffer height to configure strides.
Patch 4 change to use values from SPS/PPS control to configure the HW.
Patch 5 remove an unnecessary call to validate sps at streaming start.

Patch 6-9 refactor code to support validation and filtering of CAPUTRE
formats based on codec ops.

Patch 10 adds final bits to support H.264 High 10 and 4:2:2 profiles.

Changes in v3:
- Drop merged patches
- Use bpp and bpp_div instead of prior misuse of block_w/block_h
- New patch to use values from SPS/PPS control to configure the HW
- New patch to remove an unnecessary call to validate sps at streaming start
- Reworked pixel format validation

Changes in v2:
- Collect r-b tags
- SPS pic width and height in mbs validation moved to rkvdec_try_ctrl
- New patch to not override output buffer sizeimage
- Reworked pixel format validation
- Only align decoded buffer instead of changing frmsize step_width

Following drm-misc commits adds support for NV15/NV20/NV30 to VOP driver:
728c15b4b5f3 ("drm/fourcc: Add NV20 and NV30 YUV formats")
d4b384228562 ("drm/rockchip: vop: Add NV15, NV20 and NV30 support")

To fully runtime test this series you may need above drm commits and ffmpeg
patches from [2], this series and drm patches is also available at [3].
