From d41ef54027cc6e0697e5b77d7da393998bed7ee4 Mon Sep 17 00:00:00 2001 From: Chao Xie Date: Fri, 31 Oct 2014 10:13:53 +0800 Subject: arm: mmp: Make use of the DT supported clock Change the dtsi and dts file, soc initialization code to make use of DT support clock. So now in the code we do only need call of_clk_init to initialize the clocks.
