Add PM handlers for System suspend/resume. As DMA driver doesn't yet support suspend/resume we free up the DMA channels at suspend and acquire and initialize them at resume. Move the init/free dma calls to ndo_open/close() hooks so it is symmetric and easier to invoke from suspend/resume handler. As CPTS looses contect during suspend/resume, invoke the necessary CPTS suspend/resume helpers. Signed-off-by: Roger Quadros <rogerq@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>
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.
