Hello,

This patch series aims to bring H.264 support as well as compliance update
to the amlogic stateful video decoder driver.

The issue in the V1 patchset at [1] is solved by patch #1 following comments
and requirements from hans. It moves the full draining & stopped state tracking
and handling from vicodec to core v4l2-mem2mem.

The vicodec changes still passes the v4l2-utils "media-test" tests, log at [5]:

With this, it also passes vdec v4l2-compliance with H264 streaming on Amlogic G12A
and Amlogic SM1 SoCs successfully.

The compliance log is:
