X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d0e7a0ca4b57483e424334c453818529148baafd;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.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.
