1*4731a431SDavid DaneyISL12026 I2C RTC/EEPROM 2*4731a431SDavid Daney 3*4731a431SDavid DaneyISL12026 is an I2C RTC/EEPROM combination device. The RTC and control 4*4731a431SDavid Daneyregisters respond at bus address 0x6f, and the EEPROM array responds 5*4731a431SDavid Daneyat bus address 0x57. The canonical "reg" value will be for the RTC portion. 6*4731a431SDavid Daney 7*4731a431SDavid DaneyRequired properties supported by the device: 8*4731a431SDavid Daney 9*4731a431SDavid Daney - "compatible": must be "isil,isl12026" 10*4731a431SDavid Daney - "reg": I2C bus address of the device (always 0x6f) 11*4731a431SDavid Daney 12*4731a431SDavid DaneyOptional properties: 13*4731a431SDavid Daney 14*4731a431SDavid Daney - "isil,pwr-bsw": If present PWR.BSW bit must be set to the specified 15*4731a431SDavid Daney value for proper operation. 16*4731a431SDavid Daney 17*4731a431SDavid Daney - "isil,pwr-sbib": If present PWR.SBIB bit must be set to the specified 18*4731a431SDavid Daney value for proper operation. 19*4731a431SDavid Daney 20*4731a431SDavid Daney 21*4731a431SDavid DaneyExample: 22*4731a431SDavid Daney 23*4731a431SDavid Daney rtc@6f { 24*4731a431SDavid Daney compatible = "isil,isl12026"; 25*4731a431SDavid Daney reg = <0x6f>; 26*4731a431SDavid Daney isil,pwr-bsw = <0>; 27*4731a431SDavid Daney isil,pwr-sbib = <1>; 28*4731a431SDavid Daney } 29
