Subject: [PATCH v2 26/34] media: iris: implement vb2 streaming ops on capture and output planes
During stream on, set some mandatory properties
to firmware to start a session. Subscribe for different
bitstream parameters to get notified for change in any of
the subscribed parameters. Set all v4l2 properties set
by client, to firmware prepared with the dependency graph.
Also, configure the hardware internal buffers required
for frame processing. Send HFI_CMD_START on capture and
output planes to start the processing on respective planes.
The instance state is changed accordingly.
During stream off, send HFI_CMD_STOP to firmware which is
a synchronous command. After the response is received from
firmware, the session is closed on firmware and
instance state is changed accordingly.
