[PATCH v2 00/12] media: rkvdec: Add H.264 High 10 and 4:2:2 profile support

[Jonas Karlman]

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

Patch 1 and 3 fixes two issues when decoding field encoded content. Patch 2
ensures CAPTURE buffer is same resolution or larger than OUTPUT buffer.

Patch 5 allows userspace to set OUTPUT sizeimage.

Patch 6 updates the v4l2_format helpers to consider block width and height
when calculating plane bytesperline and sizeimage.

Patch 7 adds two new pixelformats for 10-bit 4:2:0/4:2:2.

Patch 8 change to use bytesperline and buffer height to configure strides.

Patch 9 and 10 add support for limit/lock down a pixelformat based on SPS.

Patch 11 adds final bits to support H.264 High 10 and 4:2:2 profiles.

Patch 12 adds profile and level controls.

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
See indivitual patch for changes.

This series depend on the "handle unsupported H.264 bitstreams" series at [1]
with a small fixup, s/p_cur/p_new/.

To fully runtime test this series you may need drm patches from [2] and
ffmpeg patches from [3], this series and drm patches is also available at [4].
