1 Abracon ABX80X I2C ultra low power RTC/Alarm chip
3 The Abracon ABX80X family consist of the ab0801, ab0803, ab0804, ab0805, ab1801,
4 ab1803, ab1804 and ab1805. The ab0805 is the superset of ab080x and the ab1805
5 is the superset of ab180x.
9 - "compatible": should one of:
20 Using "abracon,abx80x" will enable chip autodetection.
21 - "reg": I2C bus address of the device
25 The abx804 and abx805 have a trickle charger that is able to charge the
26 connected battery or supercap. Both the following properties have to be defined
27 and valid to enable charging:
29 - "abracon,tc-diode": should be "standard" (0.6V) or "schottky" (0.3V)
30 - "abracon,tc-resistor": should be <0>, <3>, <6> or <11>. 0 disables the output
31 resistor, the other values are in kOhm.
