During an audio playback session it is observed that, audio goes off after few seconds of continuous pause and play. No audio is heard even when the playback is resumed. The reason for above is, currently ADMA driver does not handle DMA_PAUSE/ DMA_RESUME and relevant callbacks for dma_device are not implemented. This patch implements device_pause and device_resume callbacks for the device. During pause TRANSFER_PAUSE bit of dma channel control register is set and the same is cleared during resume.

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.
