1Abracon ABX80X I2C ultra low power RTC/Alarm chip
2
3The Abracon ABX80X family consist of the ab0801, ab0803, ab0804, ab0805, ab1801,
4ab1803, ab1804 and ab1805. The ab0805 is the superset of ab080x and the ab1805
5is the superset of ab180x.

7Required properties:
8
9 - "compatible": should one of:
10        "abracon,abx80x"
11        "abracon,ab0801"
12        "abracon,ab0803"
13        "abracon,ab0804"
14        "abracon,ab0805"
15        "abracon,ab1801"
16        "abracon,ab1803"
17        "abracon,ab1804"
18        "abracon,ab1805"
19        "microcrystal,rv1805"
20	Using "abracon,abx80x" will enable chip autodetection.
21 - "reg": I2C bus address of the device

23Optional properties:
24
25The abx804 and abx805 have a trickle charger that is able to charge the
26connected battery or supercap. Both the following properties have to be defined
27and valid to enable charging:
28
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.
