TI BQ24735 Charge Controller
|
|
~~~~~~~~~~
|
|
|
|
Required properties :
|
|
- compatible : "ti,bq24735"
|
|
|
|
Optional properties :
|
|
- interrupts : Specify the interrupt to be used to trigger when the AC
|
|
adapter is either plugged in or removed.
|
|
- ti,ac-detect-gpios : This GPIO is optionally used to read the AC adapter
|
|
presence. This is a Host GPIO that is configured as an input and
|
|
connected to the bq24735.
|
|
- ti,charge-current : Used to control and set the charging current. This value
|
|
must be between 128mA and 8.128A with a 64mA step resolution. The POR value
|
|
is 0x0000h. This number is in mA (e.g. 8192), see spec for more information
|
|
about the ChargeCurrent (0x14h) register.
|
|
- ti,charge-voltage : Used to control and set the charging voltage. This value
|
|
must be between 1.024V and 19.2V with a 16mV step resolution. The POR value
|
|
is 0x0000h. This number is in mV (e.g. 19200), see spec for more information
|
|
about the ChargeVoltage (0x15h) register.
|
|
- ti,input-current : Used to control and set the charger input current. This
|
|
value must be between 128mA and 8.064A with a 128mA step resolution. The
|
|
POR value is 0x1000h. This number is in mA (e.g. 8064), see the spec for
|
|
more information about the InputCurrent (0x3fh) register.
|
|
- ti,external-control : Indicates that the charger is configured externally
|
|
and that the host should not attempt to enable/disable charging or set the
|
|
charge voltage/current.
|
|
|
|
Example:
|
|
|
|
bq24735@9 {
|
|
compatible = "ti,bq24735";
|
|
reg = <0x9>;
|
|
ti,ac-detect-gpios = <&gpio 72 0x1>;
|
|
}
