Subject: [PATCH] common clk support
Date: Mon, 24 Sep 2012 13:04:29 +0200 [thread overview]
Message-ID: <1348484692-24993-1-git-send-email-s.hauer@pengutronix.de> (raw)
The following introduces common clk support based on the Linux common clk
support and switches the i.MX architecture over to use it.
For i.MX we now have real drivers for the clk support. I have taken the
approach that all clocks we need are enabled from the driver, so we do
not need to support all the gates which lowers the overhead of the clock
support quite a bit.
This series has been tested on all i.MX SoCs except the i.MX21 (which I still
don't have).
