Ideally yes.  This is obviously going to be used again.

However;
  - My fear is that it will get confused with the 'sleep' property in
    Documentation/devicetree/booting-without-of.txt.
  - Secondly, you would need to get Rob to Ack it.


Another thought, becasue this is just for enable/disable, why not we add property as "enable-sleep" of boolean type instead of u32 value type?

It is easy to describe the behavior with enable-sleep and enable-low-power-mode.

-enable-sleep:                  Boolean, when FPS event cleared
(set to LOW), resources get disabled at the sequencing event corresponding
                                        to its FPS configuration register.

-enable-low-power-mode: Boolean, when FPS event cleared
                                        (set to LOW), resources sets into
low power mode at the sequencing event corresponding to its FPS configuration
                                        register.

Both property can not be together.


Other approach is to club together
maxim,device-state-on-disabled-event : u32, describe the PMIC state
when FPS event cleared (set to LOW) whether it should go to sleep state or
low-power state.
1 = Device state is set to sleep 2 = Device state is set to low power mode. Absence of this property or other value will not change device state when FPS event
        cleared.
