Okay, so the variable in question (lets say frequency) is an 'unsigned
long' and that's how all the APIs of clock framework expect/define
it.

And you are probably saying that we do this:

unsigned long freq;

debugfs_create_u64((u64 *)&freq);

Right? Or are you asking to update clock APIs to be converted to u64?

This will break things on a 32 bit architecture where unsigned long is
32 bits long, as doing this will overwrite the next 32 bits:

*freq = XYZ;
