1Intersil ISL1209/19 I2C RTC/Alarm chip with event in 2 3ISL12X9 have additional pins EVIN and #EVDET for tamper detection, while the 4ISL1208 and ISL1218 do not. They are all use the same driver with the bindings 5described here, with chip specific properties as noted. 6 7Required 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 15Optional 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 27Example isl1219 node with #IRQ pin connected to SoC gpio1 pin12 and #EVDET pin 28connected to SoC gpio2 pin 24 and internal pull-up enabled in EVIN pin. 29 30 isl1219: rtc@68 { 31 compatible = "isil,isl1219"; 32 reg = <0x68>; 33 interrupt-names = "irq", "evdet"; 34 interrupts-extended = <&gpio1 12 IRQ_TYPE_EDGE_FALLING>, 35 <&gpio2 24 IRQ_TYPE_EDGE_FALLING>; 36 isil,ev-evienb = <1>; 37 }; 38 39
