[PATCH v3 00/21] IPU6 multi-stream and metadata support preparation

[Sakari Ailus <sakari.ailus@linux.intel.com>]

Hi folks,

I split this set off of the metadata series as it seems it can be merged
early. Basically, it prepares the ipu6 driver for streaming multiple
streams from a single source, when the rest of the necessary patches are
merged.

All the patches in the set can be found in my metadata branch. This set
possibly depends on the metadata preparation series

I posted earlier today.

since v2:

- Fixed handling failed streamon, i.e. propagate the error in that case.

- Rework return values for ipu6_isys_csi2_streaming_change() in patch 9.

- Fix inner loop stream check in ipu6_isys_csi2_streaming_change(), in the
  same patch.

since v1:

- Fix intra-set use of v4l2_subdev_get_frame_desc().

- Address Antti's comment on assigning dt for a pin (fw term) from struct
  ipu6_isys_video. Remove vc and dt fields from the same struct, too; they
  were redundant.
