Well .... not exactly :-)

When you use the power management of the Au1xxx to enter
lower power modes, the CP0 counter stops as well.  We use the TOY
clock to keep track of system time and kernel timer interrupts
if this configuration option is selected.

The kernel timer code assumes it has access to the TOY when
CONFIG_PM is enabled.  If you intend to use TOY for something
else, make sure you don't cause trouble for the kernel timer functions.

Thanks.
