ARM: mvebu: ISL12057 rtc chip can now wake up RN102, RN102 and RN2120
Now that alarm support for ISL12057 chip is available w/ the specific
"isil,irq2-can-wakeup-machine" property, let's use that feature of the
driver dedicated to NETGEAR ReadyNAS 102, 104 and 2120 specific routing of
RTC Alarm IRQ#2 pin; on those devices, 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 this "isil,irq2-can-wakeup-machine" boolean property.
This makes 'wakealarm' sysfs entry available to configure the alarm.
