No, this is not how you use the clk API. You do not pass clock names via
platform data.
You pass clk_get() the struct device. You then pass clk_get() a
_connection id_ on that _device_ if you have more than one struct clk
associated with the _device_. You then use clkdev to associate the
struct device plus the connection id with the appropriate struct clk.
