SPI hibernation is now supported with the latest hibernation/wake
sequences in the shared ASoC code.
This has a functional dependency on two commits:
commit 3df761bdbc8b ("ASoC: cs35l56: Wake transactions need to be issued
twice")
commit a47cf4dac7dc ("ASoC: cs35l56: Change hibernate sequence to use
allow auto hibernate")
To protect against this, enabling hibernation is conditional on
CS35L56_WAKE_HOLD_TIME_US being defined, which indicates that the new
hibernation sequences are available.

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.
