Some newer Marvell SoCs support an "unstuck" function for I2C bus recovery. This is an alternative to the generic GPIO based recovery that the older SoCs use. The unstuck register falls outside of the usual address block for the I2C controller so requires an additional cell in the register property. This is optional and does not need to be supplied.
