[PATCH RFC v2 00/10] media: hantro: H264 fixes and improvements

[Jonas Karlman]

This series contains fixes and improvements for the hantro H264 decoder.

Patch 1-3 is updated patches from the "media: hantro: Collected fixes for v5.4"
series.

Patch 4-8 fixes issues and limitations observed when preparing support
for field encoded content.

Patch 9 introduce new DPB entry flags that is used to signal how a reference
frame is referenced. This information is needed to correctly build a
reference list for field encoded content.

Patch 10 adds bits to handle field encoded content, this is a rough patch
and should be reworked with proper code style and formatting.
Please get back with feedback on how to improve this.

The following samples from [1] are now playable with this series
- H264_1080i-25-interlace_Kaesescheibchen.mkv
