-Binding for TI bq24250/bq24251/bq24257 Li-Ion Charger
-
-Required properties:
-- compatible: Should contain one of the following:
- * "ti,bq24250"
- * "ti,bq24251"
- * "ti,bq24257"
-- reg: integer, i2c address of the device.
-- interrupts: Interrupt mapping for GPIO IRQ (configure for both edges). Use in
- conjunction with "interrupt-parent".
-- 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).
-
-Optional properties:
-- pg-gpios: GPIO used for connecting the bq2425x device PG (Power Good) pin.
- This pin is not available on all devices however it should be used if
- possible as this is the recommended way to obtain the charger's input PG
- state. If this pin is not specified a software-based approach for PG
- detection is used.
-- ti,current-limit: The maximum current to be drawn from the charger's input
- (in uA). If this property is not specified, the input limit current is
- set automatically using USB D+/D- signal based charger type detection.
- 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.
-- ti,in-dpm-voltage: Configures the threshold input voltage for the dynamic
- power path management (in uV). If not specified a default of 4,360,000
- (=4.36V) is used.
-
-Example:
-
-bq24257 {
- compatible = "ti,bq24257";
- reg = <0x6a>;
- interrupt-parent = <&gpio1>;
- interrupts = <16 IRQ_TYPE_EDGE_BOTH>;
-
- pg-gpios = <&gpio1 28 GPIO_ACTIVE_HIGH>;
-
- ti,battery-regulation-voltage = <4200000>;
- ti,charge-current = <1000000>;
- ti,termination-current = <50000>;
-};
-
-Example:
-
-bq24250 {
- compatible = "ti,bq24250";
- reg = <0x6a>;

- ti,charge-current = <500000>;
- ti,termination-current = <50000>;
- ti,current-limit = <900000>;
- ti,ovp-voltage = <9500000>;
