linux_dsm_epyc7002/drivers/clk/samsung/clk-exynos4.c
Linus Torvalds 1a5700bc2d The clock framework changes for 3.16 are pretty typical: mostly clock 
driver additions and fixes. There are additions to the clock core code
 for some of the basic types (e.g. the common divider type has some fixes
 and featured added to it).
 
 One minor annoyance is a last-minute dependency that wasn't handled
 quite right. ba0fae3 in this pull request depends on
 include/dt-bindings/clock/berlin2.h, which is already in your tree via
 the arm-soc pull request. Building for the berlin platform will break
 when the clk tree is built on it's own, but merged into your master
 branch everything should be fine.
