| 2 | |
| 3 | ISL12026 is an I2C RTC/EEPROM combination device. The RTC and control |
| 4 | registers respond at bus address 0x6f, and the EEPROM array responds |
| 5 | at bus address 0x57. The canonical "reg" value will be for the RTC portion. |
| 6 | |
| 7 | Required properties supported by the device: |
| 8 | |
| 9 | - "compatible": must be "isil,isl12026" |
| 10 | - "reg": I2C bus address of the device (always 0x6f) |
| 11 | |
| 12 | Optional properties: |
| 13 | |
| 14 | - "isil,pwr-bsw": If present PWR.BSW bit must be set to the specified |
| 15 | value for proper operation. |
| 16 | |
| 17 | - "isil,pwr-sbib": If present PWR.SBIB bit must be set to the specified |
| 18 | value for proper operation. |
| 19 | |

| 21 | Example: |
| 22 | |
| 23 | rtc@6f { |
| 24 | compatible = "isil,isl12026"; |
| 25 | reg = <0x6f>; |
| 26 | isil,pwr-bsw = <0>; |
| 27 | isil,pwr-sbib = <1>; |
| 28 | } |
