0001 Abracon ABX80X I2C ultra low power RTC/Alarm chip
0002
0003 The Abracon ABX80X family consist of the ab0801, ab0803, ab0804, ab0805, ab1801,
0004 ab1803, ab1804 and ab1805. The ab0805 is the superset of ab080x and the ab1805
0005 is the superset of ab180x.
0006
0007 Required properties:
0008
0009 - "compatible": should one of:
0010 "abracon,abx80x"
0011 "abracon,ab0801"
0012 "abracon,ab0803"
0013 "abracon,ab0804"
0014 "abracon,ab0805"
0015 "abracon,ab1801"
0016 "abracon,ab1803"
0017 "abracon,ab1804"
0018 "abracon,ab1805"
0019 "microcrystal,rv1805"
0020 Using "abracon,abx80x" will enable chip autodetection.
0021 - "reg": I2C bus address of the device
0022
0023 Optional properties:
0024
0025 The abx804 and abx805 have a trickle charger that is able to charge the
0026 connected battery or supercap. Both the following properties have to be defined
0027 and valid to enable charging:
0028
0029 - "abracon,tc-diode": should be "standard" (0.6V) or "schottky" (0.3V)
0030 - "abracon,tc-resistor": should be <0>, <3>, <6> or <11>. 0 disables the output
0031 resistor, the other values are in kOhm.
