1 | TI BQ24735 Charge Controller |
| 2 | ~~~~~~~~~~ | |
| 3 | ||
| 4 | Required properties : | |
| 5 | - compatible : "ti,bq24735" | |
| 6 | ||
| 7 | Optional properties : | |
| 8 | - interrupts : Specify the interrupt to be used to trigger when the AC | |
| 9 | adapter is either plugged in or removed. | |
| 10 | - ti,ac-detect-gpios : This GPIO is optionally used to read the AC adapter | |
| 11 | presence. This is a Host GPIO that is configured as an input and | |
| 12 | connected to the bq24735. | |
| 13 | - ti,charge-current : Used to control and set the charging current. This value | |
| 14 | must be between 128mA and 8.128A with a 64mA step resolution. The POR value | |
| 15 | is 0x0000h. This number is in mA (e.g. 8192), see spec for more information | |
| 16 | about the ChargeCurrent (0x14h) register. | |
| 17 | - ti,charge-voltage : Used to control and set the charging voltage. This value | |
| 18 | must be between 1.024V and 19.2V with a 16mV step resolution. The POR value | |
| 19 | is 0x0000h. This number is in mV (e.g. 19200), see spec for more information | |
| 20 | about the ChargeVoltage (0x15h) register. | |
| 21 | - ti,input-current : Used to control and set the charger input current. This | |
| 22 | value must be between 128mA and 8.064A with a 128mA step resolution. The | |
| 23 | POR value is 0x1000h. This number is in mA (e.g. 8064), see the spec for | |
| 24 | more information about the InputCurrent (0x3fh) register. | |

| 26 | Example: | |
| 27 | ||
| 28 | bq24735@9 { | |
| 29 | compatible = "ti,bq24735"; | |
| 30 | reg = <0x9>; | |
| 31 | ti,ac-detect-gpios = <&gpio 72 0x1>; | |
| 32 | } |
