From 160641e71899d5916a76326a77ce8097c7086bf3 Mon Sep 17 00:00:00 2001 From: Yadwinder Singh Brar Date: Tue, 11 Jun 2013 15:01:09 +0530 Subject: [PATCH] clk: samsung: Migrate exynos4 to use common samsung_clk_register_pll() This patch migrates exynos4 pll registeration to use common samsung_clk_register_pll() by intialising table of PLLs.
