This release extends UVC Gadget with the ability to provide a 'slideshow' source. This can assist in the testing of performance and capabilities of a UVC Gadget based device, by providing a known set of data frames and configurations to stream to the host. Further more this release contains: - lib/timer: Add timer infrastructure - lib/jpg-source: Constrain fps These allow sources with out a controlling device to be configured to deliver at the rate requested by the host. Finally, the Makefile 'helper' is fixed to correctly call the install target in ninja. Signed-off-by: Kieran Bingham <kieran.bingham@ideasonboard.com>

Fix the install target to supply the correct call to ninja, and ensure that it is marked as a phony target to prevent conflicts with any local files or directories of the same name.

As written the fps output by the jpg-source is unconstrained; it will simply fill buffers as quickly as the USB subsysem can handle them. This is not particularly realistic and also means that the frame rates configured (and thus expected) by the host are not being adhered to. Use the new timer infrastructure to slow down the buffer fill operation such that the frame rates seen match those configured by the host.

Some sources simply fill the buffers passed by the USB subsystem and return them as quickly as possible. Particularly with compressed formats operating at superspeed this rapidly results in unrealistic frame rates. Add infrastructure that allows us to define a specific framerate and introduce blocking calls that constrain those sources to the framerates expected by the host.

This release culminates being able to integrate many historical changes and updates that we had pending for quite some time along with some bugfixes and clean ups. Key new features already added to this release include: - SuperSpeed descriptor support - MJPEG support fixes - Update to support new gadget locations - Conversion to Meson build infrastructure - A new test pattern source generator - Support for JPEG sources - Improved logging - Commencement of control support Signed-off-by: Kieran Bingham <kieran.bingham@ideasonboard.com>
