When we shut down the amp, we need to wait for the built-in ramp-down before we can remove the TDM clocks. There is no documented status regiter to poll, so the best we can do is a delay. Datasheet says 5.9ms for ramp-down and 1.5ms between shutdown and next startup, so let's do 6ms after mute and 2ms after shutdown. That gives us a cumulative 8ms for ramp-down and guaratees the required minimum shutdown time.

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.
