Subject: [PATCH 06/26] clk: sunxi: declare OF clock provider
Date: Wed, 18 Sep 2013 19:53:39 +0200	[thread overview]
Message-ID: <1379526839-14798-7-git-send-email-sebastian.hesselbarth@gmail.com> (raw)
In-Reply-To: <1379526839-14798-1-git-send-email-sebastian.hesselbarth@gmail.com>

Common clock framework allows to register clock providers to get called
on of_clk_init() by using CLK_OF_DECLARE. This converts sunxi clock
providers to make use of it and get rid of the mach specific clk init
call. As sunxi has a bunch of independent clk provider nodes, we hook
current clock init to board compatible to make it called once.
