    1 Intersil ISL1209/19 I2C RTC/Alarm chip with event in
    2 
    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.
    6 
    7 Required properties supported by the device:
    8  - "compatible": Should be one of the following:
    9                 - "isil,isl1208"
   10                 - "isil,isl1209"
   11                 - "isil,isl1218"
   12                 - "isil,isl1219"
   13  - "reg": I2C bus address of the device
   14 
   15 Optional properties:
   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
   25         as is.
   26 
   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";
   32                 reg = <0x68>;
   33                 interrupt-names = "irq", "evdet";

   35                         <&gpio2 24 IRQ_TYPE_EDGE_FALLING>;
