I presume its valid for Ranchu support to be enabled in MIPS32 / MIPS64,
and R1 / R2 / R6 kernels? (that's fine if so, just making sure there's
no need for a require comment).

A comment to explain the purpose of the rounding would be helpful. I
presume its there just to get a more accurate value since the frequency
will always be a round value in practice.

Either way this patch looks good to me:
