There are currently two ways to specify custom DMA channel names: - through the SND_DMAENGINE_PCM_FLAG_CUSTOM_CHANNEL_NAME flag and snd_dmaengine_dai_dma_data data structure, - through chan_names field of struct snd_dmaengine_pcm_config. In order to replace the DAI DMA data method with the custom DMA config one on non-DT platforms the dmaengine_pcm_new() function is extended to also consider channel names specified in the custom DMA config. If both config->chan_names and dma_data->chan_name are provided the former will be used.

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.
