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>;

	}

description:

  The ISL12026 is a combination RTC and EEPROM device connected via I2C.

  The RTC and control registers respond at address 0x6f, while the EEPROM

  array responds at address 0x57. The "reg" property refers to the RTC

  portion of the device.
