| 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 | "microcrystal,rv1805" |
| 20 | Using "abracon,abx80x" will enable chip autodetection. |
| 21 | - "reg": I2C bus address of the device |
| 22 | |
| 23 | Optional properties: |
| 24 | |
| 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: |
| 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. |
