Subject: clk: si570: Migrate to clk_hw based OF and registration APIs
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a340dae9de5df79d1d09ab7eae6cb8bbeb77b996;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

clk: si570: Migrate to clk_hw based OF and registration APIs

Now that we have clk_hw based provider APIs to register clks, we
can get rid of struct clk pointers while registering clks in
these drivers, allowing us to move closer to a clear split of
consumer and provider clk APIs.
