Linux kernel source tree

Reference clock could be or not be part of the power domain. If it is part of the power domain, the power domain takes care of properly setting it. In case it is not part of the power domain and full runtime PM support is available in driver the clock will not be propertly disabled/enabled at runtime. For this, keep the prepare/unprepare operations in the driver's probe()/remove() functions and move the enable/disable in runtime PM functions. By doing this, the previous ravb_runtime_nop() function was renamed ravb_runtime_suspend() and the comment was removed. A proper runtime PM resume function was added (ravb_runtime_resume()). The current driver still don't need to make any register settings on runtime suspend/resume (as expressed in the removed comment) because, currently, pm_runtime_put_sync() is called on the driver remove function. This will be changed in the next commits (that extends the runtime PM support) such that proper register settings (along with runtime resume/suspend) will be done on ravb_open()/ravb_close(). Along with it, the other clock request operations were moved close to reference clock request and prepare to have all the clock requests specific code grouped together.

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.
