I fully agree.
a) Table 16-18 in the manual mentions ips and the values given there look much
more like ips than ppc_proc_freq (25MHz?)
b) the excerpt from clock.c Wolfgang posted mentions ips as parent
c) I cannot imagine a divider wrapping around at a frequency which is inside the
range of what the processor is capable of. MII only up to 300MHz seems like a
show-stopper to me :)
d) According to the MPC5200B-manual, ipb _is_ used there (and the linux-driver
adheres to that). I'd guess those two CPUs are related enough to assume it is
ips here.

Wolfram
