You can declare the init_data on the stack, CCF makes a copy of what it needs.
For clk_mux, clk_gate and friends, yes, use devm functions is the way to go
For the struct *clk, you can also use devm. Just keep a reference on the leaf
clock to be able to call set_rate() and prepare_enable(). You don't need the

You may have a look at drivers/mmc/host/meson-gx-mmc.c. The clock scheme of this
IP is actually very clock the ethernet one.
