Linux kernel source tree
2abb0c7f98
Introduce ipa_runtime_suspend() and ipa_runtime_resume(), which encapsulate the activities necessary for suspending and resuming the IPA hardware. Call these functions from ipa_clock_get() and ipa_clock_put() when the first reference is taken or last one is dropped. When the very first clock reference is taken (for ipa_config()), setup isn't complete yet, so (as before) only the core clock gets enabled. When the last clock reference is dropped (after ipa_deconfig()), ipa_teardown() will have made the setup_complete flag false, so there too, the core clock will be stopped without affecting GSI or the endpoints. Otherwise these new functions will perform the desired suspend and resume actions once setup is complete. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: David S.

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.
