commit 7f864458e9a6d2000b726d14b3d3a706ac92a3b0 upstream.
On all platforms set_clock_selection() writes to a GRF register. This
requires certain clocks running and thus should happen before the
clocks are disabled.
This has been noticed on RK3576 Sige5, which hangs during system suspend
when trying to suspend the second network interface. Note, that
suspending the first interface works, because the second device ensures
that the necessary clocks for the GRF are enabled.

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.
