ISL12026 I2C RTC/EEPROM
|
|
|
|
ISL12026 is an I2C RTC/EEPROM combination device. The RTC and control
|
|
registers respond at bus address 0x6f, and the EEPROM array responds
|
|
at bus address 0x57. The canonical "reg" value will be for the RTC portion.
|
|
|
|
Required properties supported by the device:
|
|
|
|
- "compatible": must be "isil,isl12026"
|
|
- "reg": I2C bus address of the device (always 0x6f)
|
|
|
|
Optional properties:
|
|
|
|
- "isil,pwr-bsw": If present PWR.BSW bit must be set to the specified
|
|
value for proper operation.
|
|
|
|
- "isil,pwr-sbib": If present PWR.SBIB bit must be set to the specified
|
|
value for proper operation.
|
|
|
|
|
|
Example:
|
|
|
|
rtc@6f {
|
|
compatible = "isil,isl12026";
|
|
reg = <0x6f>;
|
|
isil,pwr-bsw = <0>;
|
|
isil,pwr-sbib = <1>;
|
|
}
