Subject: [PATCH v3 2/9] phy: ti-pipe3: move clk initialization to a separate function
Date: Tue, 15 Dec 2015 14:46:01 +0530 [thread overview]
Message-ID: <1450170968-11282-3-git-send-email-kishon@ti.com> (raw)
In-Reply-To: <1450170968-11282-1-git-send-email-kishon@ti.com>
No functional change. Moved clock initialization done in probe to a
separate function as part of cleaning up ti_pipe3_probe.
