Now that alarm support for ISL12057 chip is available, let's use a feature of the driver dedicated to NETGEAR ReadyNAS 102 specific routing of RTC IRQ#2 pin; on the device, this pin is not connected to the SoC but to a PMIC, which allows the device to be powered up when RTC alarm rings. For that to work, the chip needs to be explicitly marked as a device wakeup source using the "can-wakeup-machine" boolean property. This makes 'wakealarm' sysfs entry available to configure the alarm.
