1 | Abracon ABX80X I2C ultra low power RTC/Alarm chip |
| 2 | ||
| 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. | |
| 6 | ||
| 7 | Required 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 | Using "abracon,abx80x" will enable chip autodetection. | |
| 20 | - "reg": I2C bus address of the device | |
| 21 | ||
| 22 | Optional properties: | |
| 23 | ||
| 24 | The abx804 and abx805 have a trickle charger that is able to charge the | |
| 25 | connected battery or supercap. Both the following properties have to be defined | |
| 26 | and valid to enable charging: | |
| 27 | ||
| 28 | - "abracon,tc-diode": should be "standard" (0.6V) or "schottky" (0.3V) | |
| 29 | - "abracon,tc-resistor": should be <0>, <3>, <6> or <11>. 0 disables the output | |
| 30 | resistor, the other values are in ohm. |
