Add support for subdev internal routing. A route is defined as a single stream from a sink pad to a source pad. The userspace can configure the routing via two new ioctls, VIDIOC_SUBDEV_G_ROUTING and VIDIOC_SUBDEV_S_ROUTING, and subdevs can implement the functionality with v4l2_subdev_pad_ops.set_routing(). - Add sink and source streams for multiplexed links - Copy the argument back in case of an error. This is needed to let the caller know the number of routes. - Expand and refine documentation. - Make the 'routes' pointer a __u64 __user pointer so that a compat32 version of the ioctl is not required. - Add struct v4l2_subdev_krouting to be used for subdevice operations. - Fix typecasing warnings - Check sink & source pad types - Add 'which' field - Routing to subdev state - Dropped get_routing subdev op Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Michal Simek <michal.simek@xilinx.com> Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> Signed-off-by: Jacopo Mondi <jacopo+renesas@jmondi.org> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@kernel.org> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
