This adds external DMA controller driver implemented in Socionext UniPhier SoCs. This driver supports DMA_MEMCPY and DMA_SLAVE modes. Since this driver does not support the the way to transfer size unaligned to burst width, 'src_maxburst' or 'dst_maxburst' of dma_slave_config must be 1 to transfer arbitrary size. If transfer size is unaligned to burst size, the transfer isn't started and the driver displays an error message.

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.
