Linux kernel source tree
c57e372b7b
Add multiplexed streams support. CAL has 8 DMA-engines and can capture 8 separate streams at the same time. The driver filters the streams based on CSI-2 virtual channel number and datatype. CAL may have (depending on the SoC) two CSI-2 RX blocks, which share the 8 DMA-engines, so the number of capturable streams does not change even if there are two CSI-2 RX blocks. Add 8 video device nodes, each representing a single DMA-engine, and set the number of source pads on CSI-2 RX blocks to 8. Each video node can be connected to any of the source pads on either of the CSI-2 RX instances using media links. CSI-2 RX block's subdevice internal routing is used to route the incoming CSI-2 streams to one of the 8 source pads. Only video data streams are supported at the moment.

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 reStructuredText 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.
