[PATCH v2 4/7] m68k: coldfire: use clkdev_lookup on most coldfire

Arnd Bergmann
2021-06-08T15:24:51Z

Coldfire is now the only target that implements the clk_get()/clk_put()
helpers itself rather than using the common implementation.

Most coldfire variants only have two distinct clocks and use the clk
code purely for lookup. Change those over to use clkdev_lookup instead
but leave the custom clk interface for those two clocks.

Also leave the four SoCs that have gated clocks.
