1ISL12026 I2C RTC/EEPROM
2
3ISL12026 is an I2C RTC/EEPROM combination device.  The RTC and control
4registers respond at bus address 0x6f, and the EEPROM array responds
5at bus address 0x57.  The canonical "reg" value will be for the RTC portion.
6
7Required properties supported by the device:
8
9 - "compatible": must be "isil,isl12026"
10 - "reg": I2C bus address of the device (always 0x6f)
11
12Optional 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.

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