Commitded1f3db4c("dmaengine: tegra210-adma: prepare for supporting newer Tegra chips") removed the default settings DMA channel RX and TX FIFO sizes and this is breaking DMA transfers. The intention was to move the default settings to the chip specific data structure because this commit was preparing for adding support for Tegra186 where the fields for the FIFO CTRL register are slightly different. Fix the configuration of the FIFO sizes by adding default values for the FIFO CTRL register for both Tegra210 and Tegra186 and store the values in the chip specific structure.

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.
