For current version, yes, it always ties system clock to rxtx5. I was just
considering if further version changes the sysclk route to another source,
the driver will simply diversify this id here for different versions.

I'll later send a v2 for it to fix the name. And you can decide which one
would be better based on what I've just explained.

Thank you,
