Subject: [PATCH V4 04/18] coresight: tmc: clearly define number of transfers per burst
Date: Tue, 26 Apr 2016 16:10:20 -0600 [thread overview]
Message-ID: <1461708634-6327-5-git-send-email-mathieu.poirier@linaro.org> (raw)
In-Reply-To: <1461708634-6327-1-git-send-email-mathieu.poirier@linaro.org>
This patch makes the name of the define reflect the amount of
data tranfers per burst, in this case 16.
