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