Fork of alistair23 Linux kernel for reMarkable from https://github.com/alistair23/linux

During probe SOF driver loads the topology, which will send messages to DSP to create the Audio components. SOF DAI component at creation time calls probe() and touches DAI registers thus we need to make sure DAI clocks are turned on during probe. Using pm_runtime_get_sync() we force resume to be called which will enable all necessary clocks. Later we call the pm_runtime_put_sync() and mark the device as autosuspend. This will cause suspend to be called which will disable all clocks to save power. Later, when userspace uses the sound card (via aplay/arecord) or any alsa-lib calls the normal runtime resume/suspend flow will happen.

README
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.
