Actually, you probably don't want this as a property in the device
tree. It doesn't describe hardware. A Kconfig option might be
warranted though.
In general it is valid to have properties

Why don't you |MSR_WE|MSR_EE at the same time?
You technically can do this. But the

Add idle power save for ppc 4xx
This patch sets the wait state MSR when power_save is called in cpu_idle loop

Add idle power save for ppc 4xx
This patch sets the wait state MSR when power_save is called in
cpu_idle loop for ppc4xx. This is mainly to help out virtualization
solutions such as KVM. This way the virtualization soultions are able
to tell if the guest kernel is idle

Could you define a property in the CPU node there that can be parsed to
use the power_save function instead of always making it the default?
