1 Intersil ISL1209/19 I2C RTC/Alarm chip with event in
3 ISL12X9 have additional pins EVIN and #EVDET for tamper detection, while the
4 ISL1208 and ISL1218 do not. They are all use the same driver with the bindings
5 described here, with chip specific properties as noted.
7 Required properties supported by the device:
8 - "compatible": Should be one of the following:
13 - "reg": I2C bus address of the device
16 - "interrupt-names": list which may contains "irq" and "evdet"
17 evdet applies to isl1209 and isl1219 only
18 - "interrupts": list of interrupts for "irq" and "evdet"
19 evdet applies to isl1209 and isl1219 only
20 - "isil,ev-evienb": Enable or disable internal pull on EVIN pin
21 Applies to isl1209 and isl1219 only
22 Possible values are 0 and 1
23 Value 0 enables internal pull-up on evin pin, 1 disables it.
24 Default will leave the non-volatile configuration of the pullup
27 Example isl1219 node with #IRQ pin connected to SoC gpio1 pin12 and #EVDET pin
28 connected to SoC gpio2 pin 24 and internal pull-up enabled in EVIN pin.
31 compatible = "isil,isl1219";
