[PATCH 0/9] libcamera: v4l2_subdevice: Prepare for embedded data support

[Laurent Pinchart]

Hello,

This patch series prepares the V4L2Subdevice class for embedded data
support. It is part of my ongoing CameraSensor rework to support
embedded data. I decided to send it separately to get early reviews of
the design, as changes will impact the rest of the work that I'm
building on top.

The most important new features are exposing MediaBusFormatInfo
internally (3/9), extending it with a format type (4/9) and adding
stream support to the format and selection rectangle get/set handlers
(7/9). Please see individual patches for details.
