This patch adds support for dynamic pipelines with multi-core by using the platform-specific core_get/put() ops to power up/down a core when a widget is set up/freed. Along with this, a few redundant functions are removed: 1. sof_pipeline_core_enable() is no longer needed as the pipeline core will be set up when the pipeline widget is set up 2. sof_core_enable() is replaced with snd_sof_core_get() 4. core_power_up/down() DSP ops are deprecated and replaced with core get/put ops. 5. Core power down in sof_widget_unload() during topology removal is also removed as it is not really needed. For dynamic pipelines, the cores will be powered off when they are not used. For static pipelines, the cores will be powered off in the device remove callback.

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.
