commit 7965d7add126883e052972d698a7bfd972d0e174 Author: David Hendricks dhendrix@chromium.org Date: Sat Jun 15 19:22:06 2013 -0700
exynos5420: add I2C8-10 to clock_get_periph_rate()
This adds entries for I2C8-10 to giant switch statement in clock_get_periph_rate(). It also eliminates the I2C peripheral's usage of clk_bit_info since it's confusing and error-prone.
