[PATCH 12/31] clk: mediatek: pll: Split definitions into separate header file

Tue Jan 25 22:06:20 PST 2022
> When the PLL type clk was implemented in the MediaTek clk driver
> library, the data structure definitions and function declaration
> were put in the common header file.
>
> Since it is its own type of clk, and not all platform clk drivers
> utilize it, having the definitions in the common header results
> in wasted cycles during compilation.
>
> Split out the related definitions and declarations into its own
> header file, and include that only in the platform clk drivers that
> need it.
