This GPIO is optionally used to read the AC adapter status. This is a Host GPIO
that is configured as an input and connected to the ACOK pin on the bq24735.
Note: for backwards compatibility reasons, the GPIO must be active on AC adapter
absence despite ACOK being active (high) on AC adapter presence.

$ref: /schemas/types.yaml#/definitions/uint32
description: |
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:
$ref: /schemas/types.yaml#/definitions/uint32
description: |
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:
$ref: /schemas/types.yaml#/definitions/uint32
description: |
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.

Indicates that the charger is configured externally and that the host should not

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
status. This is a Host GPIO that is configured as an input and connected
to the ACOK pin on the bq24735. Note: for backwards compatibility reasons,
the GPIO must be active on AC adapter absence despite ACOK being active
(high) on AC adapter presence.
- 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.
- poll-interval : In case 'interrupts' is not specified, poll AC adapter
presence with this interval (milliseconds).
Example:
bq24735@9 {
compatible = "ti,bq24735";
reg = <0x9>;
ti,ac-detect-gpios = <&gpio 72 0x1>;
