[ Upstream commitc24a5c735f] The commit080edf75d3("dmaengine: hsu: set HSU_CH_MTSR to memory width") has been mistakenly submitted. The further investigations show that the original code does better job since the memory side transfer size has never been configured by DMA users. As per latest revision of documentation: "Channel minimum transfer size (CHnMTSR)... For IOSF UART, maximum value that can be programmed is 64 and minimum value that can be programmed is 1." This reverts commit080edf75d3.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
