18c2ecf20Sopenharmony_ciIntersil ISL1209/19 I2C RTC/Alarm chip with event in 28c2ecf20Sopenharmony_ci 38c2ecf20Sopenharmony_ciISL12X9 have additional pins EVIN and #EVDET for tamper detection, while the 48c2ecf20Sopenharmony_ciISL1208 and ISL1218 do not. They are all use the same driver with the bindings 58c2ecf20Sopenharmony_cidescribed here, with chip specific properties as noted. 68c2ecf20Sopenharmony_ci 78c2ecf20Sopenharmony_ciRequired properties supported by the device: 88c2ecf20Sopenharmony_ci - "compatible": Should be one of the following: 98c2ecf20Sopenharmony_ci - "isil,isl1208" 108c2ecf20Sopenharmony_ci - "isil,isl1209" 118c2ecf20Sopenharmony_ci - "isil,isl1218" 128c2ecf20Sopenharmony_ci - "isil,isl1219" 138c2ecf20Sopenharmony_ci - "reg": I2C bus address of the device 148c2ecf20Sopenharmony_ci 158c2ecf20Sopenharmony_ciOptional properties: 168c2ecf20Sopenharmony_ci - "interrupt-names": list which may contains "irq" and "evdet" 178c2ecf20Sopenharmony_ci evdet applies to isl1209 and isl1219 only 188c2ecf20Sopenharmony_ci - "interrupts": list of interrupts for "irq" and "evdet" 198c2ecf20Sopenharmony_ci evdet applies to isl1209 and isl1219 only 208c2ecf20Sopenharmony_ci - "isil,ev-evienb": Enable or disable internal pull on EVIN pin 218c2ecf20Sopenharmony_ci Applies to isl1209 and isl1219 only 228c2ecf20Sopenharmony_ci Possible values are 0 and 1 238c2ecf20Sopenharmony_ci Value 0 enables internal pull-up on evin pin, 1 disables it. 248c2ecf20Sopenharmony_ci Default will leave the non-volatile configuration of the pullup 258c2ecf20Sopenharmony_ci as is. 268c2ecf20Sopenharmony_ci 278c2ecf20Sopenharmony_ciExample isl1219 node with #IRQ pin connected to SoC gpio1 pin12 and #EVDET pin 288c2ecf20Sopenharmony_ciconnected to SoC gpio2 pin 24 and internal pull-up enabled in EVIN pin. 298c2ecf20Sopenharmony_ci 308c2ecf20Sopenharmony_ci isl1219: rtc@68 { 318c2ecf20Sopenharmony_ci compatible = "isil,isl1219"; 328c2ecf20Sopenharmony_ci reg = <0x68>; 338c2ecf20Sopenharmony_ci interrupt-names = "irq", "evdet"; 348c2ecf20Sopenharmony_ci interrupts-extended = <&gpio1 12 IRQ_TYPE_EDGE_FALLING>, 358c2ecf20Sopenharmony_ci <&gpio2 24 IRQ_TYPE_EDGE_FALLING>; 368c2ecf20Sopenharmony_ci isil,ev-evienb = <1>; 378c2ecf20Sopenharmony_ci }; 388c2ecf20Sopenharmony_ci 39
