With assert() idea you mean define a header(i.e. imx-clk-names-id.h) like:
```
#define IMX_CLK_NAME_PER	0
#define IMX_CLK_NAME_IPG	1
...
```

And then in non-OF_PLATDATA trying to:
```
struct clk per_clk;
int ret;

ret = clk_get_by_index(dev, IMX_CLK_NAME_PER, &clk);
```

And check if clock's name is "per"?
