- NTC resister is external to battery and 'btemp' signal is used
- for thermal measurement.

-
-The lt3651 outputs are open-drain type and active low. The driver assumes the

-connected directly, the GPIO flags should be set to active low also.
-
-The driver will attempt to aquire interrupts for all GPIOs to detect changes in

-cannot report changes and userspace will need to periodically read the sysfs

-Required properties:

- number compatible string might be used in order to take care of vendor
- specific registers.
-- reg: integer, i2c address of the device. Should be <0xa>.

- See "gpio-specifier" in .../devicetree/bindings/gpio/gpio.txt.
-- #gpio-cells: Should be <2>. The first cell is the pin number, the second cell
- is used to specify optional parameters:
- See "gpio-specifier" in .../devicetree/bindings/gpio/gpio.txt.

-From OS view the device is basically an i2c-mux used to communicate with up to
-four smart battery devices at address 0xb. The driver actually implements this
-behaviour. So standard i2c-mux nodes can be used to register up to four slave
-batteries. Channels will be numerated starting from 1 to 4.

+AB85000 PMIC contains a node, which contains shared

+The node has no compatible property.
+
+Properties of this node are:

+thermistor-on-batctrl:
+ A boolean value indicating thermistor interface to battery
+
+ Note:
+ 'btemp' and 'batctrl' are the pins interfaced for battery temperature
+ measurement, 'btemp' signal is used when NTC(negative temperature
+ coefficient) resister is interfaced external to battery whereas
+ 'batctrl' pin is used when NTC resister is internal to battery.
+
+ Example:
+ ab8500_battery: ab8500_battery {
+ thermistor-on-batctrl;
+ };
+ indicates: NTC resister is internal to battery, 'batctrl' is used
+ for thermal measurement.
+
+ The absence of property 'thermal-on-batctrl' indicates
+ NTC resister is external to battery and 'btemp' signal is used
+ for thermal measurement.

-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>;
- }
