1 | Binding for TI bq2415x Li-Ion Charger |
| 2 | ||
| 3 | Required properties: | |
| 4 | - compatible: Should contain one of the following: | |
| 5 | * "ti,bq24150" | |
| 6 | * "ti,bq24150" | |
| 7 | * "ti,bq24150a" | |
| 8 | * "ti,bq24151" | |
| 9 | * "ti,bq24151a" | |
| 10 | * "ti,bq24152" | |
| 11 | * "ti,bq24153" | |
| 12 | * "ti,bq24153a" | |
| 13 | * "ti,bq24155" | |
| 14 | * "ti,bq24156" | |
| 15 | * "ti,bq24156a" | |
| 16 | * "ti,bq24158" | |
| 17 | - reg: integer, i2c address of the device. | |
| 18 | - ti,current-limit: integer, initial maximum current charger can pull | |
| 19 | from power supply in mA. | |
| 20 | - ti,weak-battery-voltage: integer, weak battery voltage threshold in mV. | |
| 21 | The chip will use slow precharge if battery voltage | |
| 22 | is below this value. | |
| 23 | - ti,battery-regulation-voltage: integer, maximum charging voltage in mV. | |
| 24 | - ti,charge-current: integer, maximum charging current in mA. | |
| 25 | - ti,termination-current: integer, charge will be terminated when current in | |
| 26 | constant-voltage phase drops below this value (in mA). | |
| 27 | - ti,resistor-sense: integer, value of sensing resistor in milliohm. | |
| 28 | ||
| 29 | Optional properties: | |
| 30 | - ti,usb-charger-detection: phandle to usb charger detection device. | |
| 31 | (required for auto mode) | |
| 32 | ||
| 33 | Example from Nokia N900: | |
| 34 | ||
| 35 | bq24150a { | |
| 36 | compatible = "ti,bq24150a"; | |
| 37 | reg = <0x6b>; | |
| 38 | ||
| 39 | ti,current-limit = <100>; | |
| 40 | ti,weak-battery-voltage = <3400>; | |
| 41 | ti,battery-regulation-voltage = <4200>; | |
| 42 | ti,charge-current = <650>; | |
| 43 | ti,termination-current = <100>; | |
| 44 | ti,resistor-sense = <68>; | |
| 45 | ||
| 46 | ti,usb-charger-detection = <&isp1704>; | |
