"x-powers,axp221-ac-power-supply"
|

"x-powers,axp813-ac-power-supply"
|
||||
|
||||
This node is a subnode of the axp20x PMIC.
|
||||
|
||||
The AXP20X can read the current current and voltage supplied by AC by
|
||||
reading ADC channels from the AXP20X ADC.
|
||||
|
||||
The AXP22X is only able to tell if an AC power supply is present and
|
||||
usable.
|
||||
|
||||
AXP813/AXP803 are able to limit current and supply voltage
|
||||
|
||||
Example:
|
||||
|
||||
&axp209 {
|

This node is a subnode of its respective PMIC DT node.
|
||||
|
||||
The supported devices can read the battery voltage, charge and discharge
|

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.
|
||||
|
||||
Example:
|
||||
|
||||
bat: battery {
|
||||
compatible = "simple-battery";
|
||||
precharge-current-microamp = <256000>;
|
||||
charge-term-current-microamp = <128000>;
|

// etc.

- compatible: Should contain one of the following:
|
||||
* "ti,bq24250"
|
||||
* "ti,bq24251"
|
||||
* "ti,bq24257"
|

- interrupts: Interrupt mapping for GPIO IRQ (configure for both edges). Use in
|
||||
conjunction with "interrupt-parent".
|

||||
If the hardware does not support the D+/D- based detection, a default
|
||||
of 500,000 is used (=500mA) instead.
|
||||
- ti,ovp-voltage: Configures the over voltage protection voltage (in uV). If
|
||||
not specified a default of 6,5000,000 (=6.5V) is used.

|
||||
power path management (in uV). If not specified a default of 4,360,000
|
||||
(=4.36V) is used.

Binding for TI bq25890 Li-Ion Charger
|
||||
|
||||
This driver will support the bq25892, the bq25896 and the bq25890. There are
|
||||
other ICs in the same family but those have not been tested.
|
||||
|
||||
Required properties:
|
||||
- compatible: Should contain one of the following:
|
||||
* "ti,bq25890"
|
||||
* "ti,bq25892"
|
||||
* "ti,bq25895"
|
||||
* "ti,bq25896"
|
||||
- reg: integer, i2c address of the device.
|
||||
- interrupts: interrupt line;
|
||||
- ti,battery-regulation-voltage: integer, maximum charging voltage (in uV);
|
||||
- ti,charge-current: integer, maximum charging current (in uA);
|
||||
- ti,termination-current: integer, charge will be terminated when current in
|
||||
constant-voltage phase drops below this value (in uA);
|
||||
- ti,precharge-current: integer, maximum charge current during precharge
|
||||
phase (in uA);
|
||||
- ti,minimum-sys-voltage: integer, when battery is charging and it is below
|
||||
minimum system voltage, the system will be regulated above
|
||||
minimum-sys-voltage setting (in uV);
|
||||
- ti,boost-voltage: integer, VBUS voltage level in boost mode (in uV);
|
||||
- ti,boost-max-current: integer, maximum allowed current draw in boost mode
|
||||
(in uA).
|
||||
|
||||
Optional properties:
|
||||
- ti,boost-low-freq: boolean, if present boost mode frequency will be 500kHz,
|
||||
otherwise 1.5MHz;
|
||||
- ti,use-ilim-pin: boolean, if present the ILIM resistor will be used and the
|
||||
input current will be the lower between the resistor setting and the IINLIM
|
||||
register setting;
|
||||
- ti,thermal-regulation-threshold: integer, temperature above which the charge
|
||||
current is lowered, to avoid overheating (in degrees Celsius). If omitted,
|
||||
the default setting will be used (120 degrees);
|
||||
- ti,ibatcomp-micro-ohms: integer, value of a resistor in series with
|
||||
the battery;
|
||||
- ti,ibatcomp-clamp-microvolt: integer, maximum charging voltage adjustment due
|
||||
to expected voltage drop on in-series resistor;
|

Analog Devices LT3651 Charger Power Supply bindings: lt3651-charger
|
||||
|
||||
Required properties:
|
||||
- compatible: Should contain one of the following:
|
||||
* "lltc,ltc3651-charger", (DEPRECATED: Use "lltc,lt3651-charger")
|
||||
* "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 {
|

lltc,acpr-gpios = <&gpio0 68 GPIO_ACTIVE_LOW>;

negative value when the battery has been connected to the wrong end of the
|
||||
resistor.
|
||||
- lltc,prescaler-exponent: The prescaler exponent as explained in the datasheet.
|
||||
This determines the range and accuracy of the gauge. The value is programmed
|
||||
into the chip only if it differs from the current setting. The setting is
|
||||
lost when the battery is disconnected.
|
||||
|

Binding for sbs-manager
|
||||
|
||||
Required properties:
|
||||
- compatible: "<vendor>,<part-number>", "sbs,sbs-charger" as fallback. The part
|
||||
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>.
|
||||
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.

|
||||
|
||||
Required properties:
|
||||
- compatible: "<vendor>,<part-number>", "sbs,sbs-charger" as fallback. The part
|
||||
number compatible string might be used in order to take care of vendor
|
||||
specific registers.
|
||||
|
||||
Optional properties:
|
||||
- interrupts: Interrupt mapping for GPIO IRQ. Use in conjunction with
|
||||
"interrupt-parent". If an interrupt is not provided the driver will switch
|
||||
automatically to polling.
|
||||
|
||||
Example:
|
||||
|
||||
ltc4100@9 {
|
||||
compatible = "lltc,ltc4100", "sbs,sbs-charger";
|
||||
reg = <0x9>;

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>;

TWL BCI (Battery Charger Interface)
|
||||
|
||||
The battery charger needs to interact with the USB phy in order
|
||||
to know when charging is permissible, and when there is a connection
|
||||
or disconnection.
|
||||
|
||||
The choice of phy cannot be configured at a hardware level, so there
|
||||
is no value in explicit configuration in device-tree. Rather
|
||||
if there is a sibling of the BCI node which is compatible with
|
||||
"ti,twl4030-usb", then that is used to determine when and how
|
||||
use USB power for charging.
|
||||
|
||||
Required properties:
|
||||
- compatible:
|
||||
- "ti,twl4030-bci"
|
||||
- interrupts: two interrupt lines from the TWL SIH (secondary
|
||||
interrupt handler) - interrupts 9 and 2.
|
||||
|
||||
Optional properties:
|
||||
- ti,bb-uvolt: microvolts for charging the backup battery.
|
||||
- ti,bb-uamp: microamps for charging the backup battery.
