Intersil ISL1219 I2C RTC/Alarm chip with event in
|
|
|
|
ISL1219 has additional pins EVIN and #EVDET for tamper detection.
|
|
|
|
Required properties supported by the device:
|
|
|
|
- "compatible": must be "isil,isl1219"
|
|
- "reg": I2C bus address of the device
|
|
|
|
Optional properties:
|
|
|
|
- "interrupt-names": list which may contains "irq" and "evdet"
|
|
- "interrupts": list of interrupts for "irq" and "evdet"
|
|
- "isil,ev-evienb": if present EV.EVIENB bit is set to the specified
|
|
value for proper operation.
|
|
|
|
|
|
Example isl1219 node with #IRQ pin connected to SoC gpio1 pin12
|
|
and #EVDET pin connected to SoC gpio2 pin 24:
|
|
|
|
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>;
|
|
};
