-Intersil ISL1209/19 I2C RTC/Alarm chip with event in
-
-ISL12X9 have additional pins EVIN and #EVDET for tamper detection, while the
-ISL1208 and ISL1218 do not. They are all use the same driver with the bindings
-described here, with chip specific properties as noted.
-
-Required properties supported by the device:
- - "compatible": Should be one of the following:
- - "isil,isl1208"
- - "isil,isl1209"
- - "isil,isl1218"
- - "isil,isl1219"
- - "reg": I2C bus address of the device
-
-Optional properties:
- - "interrupt-names": list which may contains "irq" and "evdet"
- evdet applies to isl1209 and isl1219 only
- - "interrupts": list of interrupts for "irq" and "evdet"
- evdet applies to isl1209 and isl1219 only
- - "isil,ev-evienb": Enable or disable internal pull on EVIN pin
- Applies to isl1209 and isl1219 only
- Possible values are 0 and 1
- Value 0 enables internal pull-up on evin pin, 1 disables it.
- Default will leave the non-volatile configuration of the pullup
- as is.
-
-Example isl1219 node with #IRQ pin connected to SoC gpio1 pin12 and #EVDET pin
-connected to SoC gpio2 pin 24 and internal pull-up enabled in EVIN pin.
-
- isl1219: rtc@68 {
- compatible = "isil,isl1219";
- reg = <0x68>;
- interrupt-names = "irq", "evdet";
- interrupts-extended = <&gpio1 12 IRQ_TYPE_EDGE_FALLING>,
- <&gpio2 24 IRQ_TYPE_EDGE_FALLING>;
- isil,ev-evienb = <1>;
