Subject: [PATCH v3 6/8] ARM: at91: add clk_lookup entry for RTT devices
Date: Thu, 11 Sep 2014 10:56:05 +0200	[thread overview]
Message-ID: <1410425767-17874-7-git-send-email-boris.brezillon@free-electrons.com> (raw)
In-Reply-To: <1410425767-17874-1-git-send-email-boris.brezillon@free-electrons.com>

First export the clk32k clk.
Then add clk_lookup entries for RTT devices so that rtc-at91sam9 driver
can retrieve and manipulate the slow clk.
