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.
