From 384cb2ce819cf08fc8e7c3d306f180f0cefe4674 Mon Sep 17 00:00:00 2001 From: Chanwoo Choi Date: Mon, 27 Oct 2014 10:11:57 +0900 Subject: clk: samsung: exynos4415: Add clocks using common clock framework This patch adds clock driver of Exynos4415 SoC based on Cortex-A9 using common clock framework. The CMU (Clock Management Unit) of Exynos4415 controls PLLs(Phase Locked Loops) and generates system clocks for CPU, busses and function clocks for individual IPs.
