The NAVSS UDMA will stuck if target IP module is disabled by PM while PSI-L threads are paired UDMA<->IP and no further transfers is possible. This could be the case for IPs J721E Main CPSW (cpsw9g). Hence, to avoid such situation do PSI-L threads pairing only when UDMA channel is going to be enabled as at this time DMA consumer module expected to be active already.

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.
