Subject: [PATCH 9/9] coresight: Documenting reference to generic PD bindings
Date: Tue, 6 Jan 2015 09:37:13 -0700 [thread overview]
Message-ID: <1420562233-2015-10-git-send-email-mathieu.poirier@linaro.org> (raw)
In-Reply-To: <1420562233-2015-1-git-send-email-mathieu.poirier@linaro.org>
From: Mathieu Poirier <mathieu.poirier@linaro.org>
Each coresight block can be part of a power domain. Using the
generic power domain subsystems to manage power to individual
domains guarantes that coresight operations won't be interrupted
by other components.
Signed-off-by: Mathieu Poirier <mathieu.poirier@linaro.org>
