According to the i.MX8M Mini reference manual chapter "16.1.4.2 Generation of Start" it is only necessary to poll for bus busy and arbitration lost in multi master mode. This helps to avoid rescheduling while the i2c bus is busy and avoids SMBus devices to timeout. For backward compatibility, the single-master property needs to be explicitly set to disable the bus busy polling.

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 reStructuredText 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.
