-TI BQ24190 Li-Ion Battery Charger
-
-Required properties:
-- compatible: contains one of the following:
- * "ti,bq24190"
- * "ti,bq24192"
- * "ti,bq24192i"
- * "ti,bq24196"
-- reg: integer, I2C address of the charger.
-- interrupts[-extended]: configuration for charger INT pin.
-
-Optional properties:
-- monitored-battery: phandle of battery characteristics devicetree node
- The charger uses the following battery properties:
- + precharge-current-microamp: maximum charge current during precharge
- phase (typically 20% of battery capacity).
- + charge-term-current-microamp: a charge cycle terminates when the
- battery voltage is above recharge threshold, and the current is below
- this setting (typically 10% of battery capacity).
- See also Documentation/devicetree/bindings/power/supply/battery.txt
-- ti,system-minimum-microvolt: when power is connected and the battery is below
- minimum system voltage, the system will be regulated above this setting.
-
-child nodes:
-- usb-otg-vbus:
- Usage: optional
- Description: Regulator that is used to control the VBUS voltage direction for
- either USB host mode or for charging on the OTG port.
-
-Notes:
-- Some circuit boards wire the chip's "OTG" pin high (enabling 500mA default
- charge current on USB SDP ports, among other features). To simulate this on
- boards that wire the pin to a GPIO, set a gpio-hog.

-Required properties:
-- compatible: Should contain one of the following:

- * "lltc,lt3651-charger"
- - lltc,acpr-gpios: Connect to ACPR output. See remark below.
-
-Optional properties:
- - lltc,fault-gpios: Connect to FAULT output. See remark below.
- - lltc,chrg-gpios: Connect to CHRG output. See remark below.
-
-The lt3651 outputs are open-drain type and active low. The driver assumes the
-GPIO reports "active" when the output is asserted, so if the pins have been
-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
-line state. If the system is not capabale of providing interrupts, the driver
-cannot report changes and userspace will need to periodically read the sysfs
-attributes to detect changes.
-
-Example:
-
- charger: battery-charger {
- compatible = "lltc,lt3651-charger";
- lltc,acpr-gpios = <&gpio0 68 GPIO_ACTIVE_LOW>;

-Required properties:

-- reg: integer, i2c address of the device. Should be <0xa>.
-Optional properties:
-- gpio-controller: Marks the port as GPIO controller.
- 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.

-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).
