<content type='text'>
Introduce handling for the QC08C format in the decoder. QC08C format is
NV12 with UBWC compression. Update format checks and configuration to
enable decoding of QC08C streams.

<content type='text'>
Add supports for the G/S_PARM V4L2 ioctls for encoder video device with
necessary hooks. This allows userspace to query the current streaming
parameters such as frame intervals and set desired streaming parameters
primarily the frame rate.

<id>urn:sha1:17f2a485ca673a1d60db1cac542d35e9b50e3254</id>
<content type='text'>
Implement the vb2 ops for the buf queue. These are the different buffer
attributes:
BUF_ATTR_DEFERRED - buffer queued by the client but not submitted to
                    firmware.
BUF_ATTR_PENDING_RELEASE - buffers requested to be released from
                           the firmware.
BUF_ATTR_QUEUED - buffers submitted to the firmware.
BUF_ATTR_DEQUEUED - buffers received from the firmware.
BUF_ATTR_BUFFER_DONE - buffers sent back to vb2.

During the stream on operation, set some mandatory properties on the
firmware to start a session. Set all v4l2 properties, which are set by
the client, on to firmware, which is prepared with the dependency graph.

During the stream on operation, send HFI_CMD_START on the capture and
output planes to start processing on the respective planes.

During the stream off operation, send HFI_CMD_STOP to the firmware,
which is a synchronous command. After the response is received by the
firmware, the session is closed on the firmware.

Introduce different states for the instance and state transitions.

IRIS_INST_INIT - video instance is opened.
IRIS_INST_INPUT_STREAMING - stream on is completed on output plane.
IRIS_INST_OUTPUT_STREAMING - stream on is completed on capture plane.
IRIS_INST_STREAMING - stream on is completed on both output and capture
planes.
IRIS_INST_DEINIT - video instance is closed.
IRIS_INST_ERROR - error state.
