The lan969x SoC uses the clk-lan966x driver. Would it not make sense to select
it here?

  +       select COMMON_CLK_LAN966X

HI Daniel,
To me it made more sense to select individual drivers directly in the
config, cause we need pinctrl
etc as well and I dont think it scales selecting it directly via ARCH.
