The JZ4755 has 4 DMA channels per DMA unit, two idential DMA units.
The JZ4755 has the similar DMA engine to JZ4725b and it has the
same bug as JZ4725b, see commit a40c94be23.
At least the JZ_SOC_DATA_BREAK_LINKS flag make it work much better,
although not ideal.

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.
