Systems that depend on a active low behaviour (sirq_polarity set to 0) such as OpenPower boxes also use LPC, so this relationship does not hold. The property was added for a Tyan S7106 system which is not supported in the kernel tree. Should this or other systems wish to use this feature of the driver they should add it to the machine specific device tree.
