Use regcache_sync() to recover the registers of controller, PHY and PLL after suspend and resume. In order to recover the registers need to avoid use the *_SET, *_CLR and *_TOG registers. Recovery of the registers should be done before loading XCVR firmware otherwise some registers set by firmware are overwritten. Besides only in eARC mode is it necessary to load XCVR firmware.

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.
