| 2 | |
| 3 | Required properties: |
| 4 | - compatible: Should contain one of the following: |
| 5 | * "ti,bq25890" |
| 6 | - reg: integer, i2c address of the device. |
| 7 | - ti,battery-regulation-voltage: integer, maximum charging voltage (in uV); |
| 8 | - ti,charge-current: integer, maximum charging current (in uA); |
| 9 | - ti,termination-current: integer, charge will be terminated when current in |
| 10 | constant-voltage phase drops below this value (in uA); |
| 11 | - ti,precharge-current: integer, maximum charge current during precharge |
| 12 | phase (in uA); |
| 13 | - ti,minimum-sys-voltage: integer, when battery is charging and it is below |
| 14 | minimum system voltage, the system will be regulated above |
| 15 | minimum-sys-voltage setting (in uV); |
| 16 | - ti,boost-voltage: integer, VBUS voltage level in boost mode (in uV); |
| 17 | - ti,boost-max-current: integer, maximum allowed current draw in boost mode |
| 18 | (in uA). |
| 19 | |
| 20 | Optional properties: |
| 21 | - ti,boost-low-freq: boolean, if present boost mode frequency will be 500kHz, |
| 22 | otherwise 1.5MHz; |
| 23 | - ti,use-ilim-pin: boolean, if present the ILIM resistor will be used and the |
| 24 | input current will be the lower between the resistor setting and the IINLIM |
| 25 | register setting; |
| 26 | - ti,thermal-regulation-threshold: integer, temperature above which the charge |
| 27 | current is lowered, to avoid overheating (in degrees Celsius). If omitted, |
| 28 | the default setting will be used (120 degrees); |
| 29 | |
