[PATCH 0/2] clk: samsung: exynos5420: Add clocks for CMU_CDREX domain

Dear all,

Please ignore this patches because the CMU_CDREX
should support the 800MHz DRAM clock. But, following clk_summary
show the 825MHz clock. So, I need to change the clock rate
of fout_bpll or check it. After setting the DRAM clock
as 800MHz, I'll send the patches again.

Regards,
Chanwoo Choi
