[PATCH 05/19] clk: samsung: exynos5433: Add clocks for CMU_G2D domain

Tue Dec 2 00:49:42 PST 2014
This patch adds ths mux/divider/gate clocksof CMU_G2D domain which includes
G2D/MDMA IPs. The CMU_G2D must need the clocks related to G2D by providing
CMU_TOP domain. So, this patch add several clocks for G2D from CMU_TOP domain.
