Hi Mark,
I'm really sorry about this. I completely forgot this dependency. It has been accepted in clk early in this cycle and it should be sent to Linus during the next merge window. Mike and Stephen have topic branch with related change:
git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux.git clk-core-duty-cycle
commit: 9fba738a53dd ("clk: add duty cycle support")
Again, sorry about this. Regards Jerome
