X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=d0e7a0ca4b57483e424334c453818529148baafd;p=sagit-ice-cold%2Fkernel_xiaomi_msm8998.git

clk: rockchip: setup pll_mux data earlier

In some cases we might need to access the data of the pll mux before the actual
mux gets registered - like in the following patch adding an init-callback.

Therefore populate pll_mux before registering the core pll-clock.
