Can the input clock be higher than 1 GHz?  If not, I suggest using
clocks_calc_mult_shift() with maxsec=4 and a setting the watchdog also
to 4*HZ.

On second thought, with the new 12% timer batching, using 4*HZ for 32
bits of 1 GHz is cutting it too close.  So just keep it like you had
it, with maxsec=mask/freq and timeout=maxsec/2, to stay on the safe
side.
