[PATCH v2] media: mediatek: vcodec: support stateless hevc decoder

Yunfei Dong
2023-04-28T08:23:54Z

Add mediatek hevc decoder linux driver which use the stateless API in MT8195.

Signed-off-by: Yunfei Dong <yunfei.dong@mediatek.com>
---
Changed from v1:
- fix build error when build 32bit system.
- hevc fluster test result: 132/147 (not support: 10bit => 11 and resolution => 4).
