2018-06-09v4l2: Extract video buffer structure to separate fileLaurent Pinchart
The v4l2_video_buffer structure describes a video buffer. It is used by the v4l2_device class only, but isn't otherwise tied to V4L2. To prepare for non-V4L2 video sources, extract it to a separate file and rename it to video_buffer. At the same time, add a new video_buffer_set structure to represent as set of video buffers.

2018-06-09uvc-gadget: factor out uvc protocol and stream handling codePaul Elder
uvc-gadget.c has been getting cluttered with functions related to UVC protocol handling and stream handling. Additionally, it is forseen that we might want stream handling to be modular for different system models. Factor out code related to UVC protocol handling to uvc.c (and uvc.h) and code related to stream handling to stream.c (and stream.h), and update the Makefile accordingly.

2018-05-26configfs: Provide configfs supportKieran Bingham
Parse a configuration name from the commandline, and utilise it to identify the configfs configuration path. Only the short-name (i.e. "uvc.1") is necessary to provide if there is no ambiguity regarding the gadget, otherwise the gadget path should be included ("g1/functions/uvc.1"). If the parameter is not provided then the first function is utilised. Legacy g_webcam is still supported, and the parameter will define the UDC to match against if provided.

2018-05-22v4l2: Import V4L2 support code from omap3-isp-liveLaurent Pinchart
The omap3-isp-live project [1] includes generic V4L2 support code that implements the V4L2 API. Instead of reinventing the wheel, import the code and use it. The code has been modified to merge the V4L2 buffers pool implementation in the V4L2 support code as the abstraction wasn't right for the uvc-gadget project. Further refactoring will be performed separately. The original license hasn't been modified from the original LGPL-2.1+. The sole copyright owner is Laurent Pinchart.

2018-05-21events: Import event handling library from omap3-isp-liveLaurent Pinchart
The omap3-isp-live project [1] includes a generic event handling library that implements a select-based loop. Instead of reinventing the wheel, import the library and use it. The original license hasn't been modified, and includes both GPL-2.0+ and LGPL-2.1+ code. The sole copyright owner is Laurent Pinchart.
