1*4882a593SmuzhiyunISL12026 I2C RTC/EEPROM 2*4882a593Smuzhiyun 3*4882a593SmuzhiyunISL12026 is an I2C RTC/EEPROM combination device. The RTC and control 4*4882a593Smuzhiyunregisters respond at bus address 0x6f, and the EEPROM array responds 5*4882a593Smuzhiyunat bus address 0x57. The canonical "reg" value will be for the RTC portion. 6*4882a593Smuzhiyun 7*4882a593SmuzhiyunRequired properties supported by the device: 8*4882a593Smuzhiyun 9*4882a593Smuzhiyun - "compatible": must be "isil,isl12026" 10*4882a593Smuzhiyun - "reg": I2C bus address of the device (always 0x6f) 11*4882a593Smuzhiyun 12*4882a593SmuzhiyunOptional properties: 13*4882a593Smuzhiyun 14*4882a593Smuzhiyun - "isil,pwr-bsw": If present PWR.BSW bit must be set to the specified 15*4882a593Smuzhiyun value for proper operation. 16*4882a593Smuzhiyun 17*4882a593Smuzhiyun - "isil,pwr-sbib": If present PWR.SBIB bit must be set to the specified 18*4882a593Smuzhiyun value for proper operation. 19*4882a593Smuzhiyun 20*4882a593Smuzhiyun 21*4882a593SmuzhiyunExample: 22*4882a593Smuzhiyun 23*4882a593Smuzhiyun rtc@6f { 24*4882a593Smuzhiyun compatible = "isil,isl12026"; 25*4882a593Smuzhiyun reg = <0x6f>; 26*4882a593Smuzhiyun isil,pwr-bsw = <0>; 27*4882a593Smuzhiyun isil,pwr-sbib = <1>; 28*4882a593Smuzhiyun } 29
