The point is that you can pass what ever you like. You do not need to
pass the frequency you can pass the clock handle instead.

What happens it the clk_get() of the gpmc_l3_clk fails during the init?

In fact if you migrate to runtime pm then we should not have the clk_get
in the gpmc_init any more.
