1*c66ec88fSEmmanuel VadotISL12026 I2C RTC/EEPROM 2*c66ec88fSEmmanuel Vadot 3*c66ec88fSEmmanuel VadotISL12026 is an I2C RTC/EEPROM combination device. The RTC and control 4*c66ec88fSEmmanuel Vadotregisters respond at bus address 0x6f, and the EEPROM array responds 5*c66ec88fSEmmanuel Vadotat bus address 0x57. The canonical "reg" value will be for the RTC portion. 6*c66ec88fSEmmanuel Vadot 7*c66ec88fSEmmanuel VadotRequired properties supported by the device: 8*c66ec88fSEmmanuel Vadot 9*c66ec88fSEmmanuel Vadot - "compatible": must be "isil,isl12026" 10*c66ec88fSEmmanuel Vadot - "reg": I2C bus address of the device (always 0x6f) 11*c66ec88fSEmmanuel Vadot 12*c66ec88fSEmmanuel VadotOptional properties: 13*c66ec88fSEmmanuel Vadot 14*c66ec88fSEmmanuel Vadot - "isil,pwr-bsw": If present PWR.BSW bit must be set to the specified 15*c66ec88fSEmmanuel Vadot value for proper operation. 16*c66ec88fSEmmanuel Vadot 17*c66ec88fSEmmanuel Vadot - "isil,pwr-sbib": If present PWR.SBIB bit must be set to the specified 18*c66ec88fSEmmanuel Vadot value for proper operation. 19*c66ec88fSEmmanuel Vadot 20*c66ec88fSEmmanuel Vadot 21*c66ec88fSEmmanuel VadotExample: 22*c66ec88fSEmmanuel Vadot 23*c66ec88fSEmmanuel Vadot rtc@6f { 24*c66ec88fSEmmanuel Vadot compatible = "isil,isl12026"; 25*c66ec88fSEmmanuel Vadot reg = <0x6f>; 26*c66ec88fSEmmanuel Vadot isil,pwr-bsw = <0>; 27*c66ec88fSEmmanuel Vadot isil,pwr-sbib = <1>; 28*c66ec88fSEmmanuel Vadot } 29
