Subject: [PATCH v4 1/3] interconnect: Move internal structs into a separate file
Date: Thu, 28 Nov 2019 16:18:16 +0200 [thread overview]
Message-ID: <20191128141818.32168-2-georgi.djakov@linaro.org> (raw)
In-Reply-To: <20191128141818.32168-1-georgi.djakov@linaro.org>
Move the interconnect framework internal structs into a separate file,
so that it can be included and used by ftrace code. This will allow us
to expose some more useful information in the traces.
Signed-off-by: Georgi Djakov <georgi.djakov@linaro.org>
