Subject: [PATCH 2/8] clk: max77686: Provide .recalc_rate() operation
Date: Thu, 17 Oct 2013 18:30:36 +0200	[thread overview]
Message-ID: <1382027442-1992-3-git-send-email-t.figa@samsung.com> (raw)
In-Reply-To: <1382027442-1992-1-git-send-email-t.figa-Sze3O3UU22JBDgjK7y7TUQ@public.gmane.org>

It is usually nice to know frequency of a clock, so this patch adds a
.recalc_rate() callback returning rates of provided clocks.
