Sounds good to me.

Add a comment here that these are all the clk library parts or something
like that?

And maybe add a comment here indicating that SoC drivers go below?

> obj-$(CONFIG_COMMON_CLK_MESON8B) += meson8b.o
> -obj-$(CONFIG_COMMON_CLK_GXBB) += gxbb.o gxbb-aoclk.o
> -obj-$(CONFIG_COMMON_CLK_AXG) += axg.o axg-aoclk.o
> -obj-$(CONFIG_COMMON_CLK_AXG_AUDIO) += axg-audio.o
> -obj-$(CONFIG_COMMON_CLK_REGMAP_MESON) += clk-regmap.o
> +obj-$(CONFIG_COMMON_CLK_GXBB) += gxbb.o gxbb-aoclk.o
> +obj-$(CONFIG_COMMON_CLK_AXG) += axg.o axg-aoclk.o
> +obj-$(CONFIG_COMMON_CLK_AXG_AUDIO) += axg-audio.o

And sort them by config name alphanumerically?
