| 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. |
| - interrupt-parent: Should be the phandle for the interrupt controller. Use in |
| conjunction with "interrupts". |
| - 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>; |
| interrupt-parent = <&gpio1>; |
| interrupts = <16 IRQ_TYPE_EDGE_BOTH>; |
| |
| ti,battery-regulation-voltage = <4200000>; |
| ti,charge-current = <500000>; |
| ti,termination-current = <50000>; |
| ti,current-limit = <900000>; |
| ti,ovp-voltage = <9500000>; |
| ti,in-dpm-voltage = <4440000>; |
| }; |
