Subject: [PATCH net-next 0/5] net: ipa: add clock references
Date: Tue, 27 Jul 2021 16:19:28 -0500	[thread overview]
Message-ID: <20210727211933.926593-1-elder@linaro.org> (raw)

This series continues preparation for implementing runtime power
management for IPA.  We need to ensure that the IPA core clock and
interconnects are operational whenever IPA hardware is accessed.
And in particular this means that any external entry point that can
lead to accessing IPA hardware must guarantee the hardware is "up"
when it is accessed.

The first four patches in this series take IPA clock references when
needed by such external entry points, dropping those references in
those same functions when they are no longer required.

The last patch is a bit different, though it too prepares for
enabling runtime power management.  It avoids suspending/resuming
endpoints if setup is not complete.
