[U-Boot] [PATCH] exynos: i2c: Use generic api to get i2c clk freq
From: Padmavathi Venna padma.v@samsung.com
Use generic api to get the i2c clock frequency. Tested on smdk5250 with the help of following commands. run i2c dev 1 i2c dev 2 i2c speed

Since clock_get_periph_rate did not implemented on exynos4, exynos4 will get zero. So, I'll not accept this patch.
Thanks, Minkyu Kang.
