[PATCH] clk: samsung: exynos7: Don't gate CMU_{CCORE, FSYS0} blocks clock

From: Alim Akhtar
Date: Thu Apr 14 2016 - 00:42:52 EST


This patch adds CLK_IS_CRITICAL flag to ACLK_CCORE_133 and ACLK_FSYS0_200
clocks. These clocks are critical for accessing CMU_CCORE and CMU_FSYS0
blocks registers. Let these clocks to be enabled all the time.
