Message-Id: <1396995836-31111-6-git-send-email-elder@linaro.org>
Date: Tue, 8 Apr 2014 17:23:56 -0500
From: Alex Elder <elder@...aro.org>
To: mturquette@...aro.org, mporter@...aro.org, bcm@...thebug.org,
devicetree@...r.kernel.org
Cc: linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org
Subject: [PATCH v2 5/5] ARM: dts: use real clocks for bcm21664
Replace the "fake" fixed-rate clocks used previously for the
bcm21664 family with "real" ones.
