The change below is correct, but the patch message is wrong.
The core change is commit 667464208989 ("clk: rockchip: include downstream
muxes into fractional dividers") with the second change being a fixup as the
first introduced issues. So your commit message should orient itself on the
other commit, like
------
clk: rockchip: include downstream muxes into fractional dividers on rk3368
During the initial conversion to the newly introduced combined fractional
dividers+muxes the rk3368 clocks were left out, so convert them now.
