1 Binding for TI bq24250/bq24251/bq24257 Li-Ion Charger 2 3 Required properties: 4 - compatible: Should contain one of the following: 5 * "ti,bq24250" 6 * "ti,bq24251" 7 * "ti,bq24257" 8 - reg: integer, i2c address of the device. 9 - interrupt-parent: Should be the phandle for the interrupt controller. Use in 10 conjunction with "interrupts". 11 - interrupts: Interrupt mapping for GPIO IRQ (configure for both edges). Use in 12 conjunction with "interrupt-parent". 13 - ti,battery-regulation-voltage: integer, maximum charging voltage in uV. 14 - ti,charge-current: integer, maximum charging current in uA. 15 - ti,termination-current: integer, charge will be terminated when current in 16 constant-voltage phase drops below this value (in uA). 17 18 Optional properties: 19 - pg-gpios: GPIO used for connecting the bq2425x device PG (Power Good) pin. 20 This pin is not available on all devices however it should be used if 21 possible as this is the recommended way to obtain the charger's input PG 22 state. If this pin is not specified a software-based approach for PG 23 detection is used. 24 - ti,current-limit: The maximum current to be drawn from the charger's input 25 (in uA). If this property is not specified, the input limit current is 26 set automatically using USB D+/D- signal based charger type detection. 27 If the hardware does not support the D+/D- based detection, a default 28 of 500,000 is used (=500mA) instead. 29 - ti,ovp-voltage: Configures the over voltage protection voltage (in uV). If 30 not specified a default of 6,5000,000 (=6.5V) is used. 31 - ti,in-dpm-voltage: Configures the threshold input voltage for the dynamic 32 power path management (in uV). If not specified a default of 4,360,000 33 (=4.36V) is used. 34 35 Example: 36 37 bq24257 { 38 compatible = "ti,bq24257"; 39 reg = <0x6a>; 40 interrupt-parent = <&gpio1>; 41 interrupts = <16 IRQ_TYPE_EDGE_BOTH>; 42 43 pg-gpios = <&gpio1 28 GPIO_ACTIVE_HIGH>; 44 45 ti,battery-regulation-voltage = <4200000>; 46 ti,charge-current = <1000000>; 47 ti,termination-current = <50000>; 48 }; 49 50 Example: 51 52 bq24250 { 53 compatible = "ti,bq24250"; 54 reg = <0x6a>; 55 interrupt-parent = <&gpio1>; 56 interrupts = <16 IRQ_TYPE_EDGE_BOTH>; 57 58 ti,battery-regulation-voltage = <4200000>; 59 ti,charge-current = <500000>; 60 ti,termination-current = <50000>; 61 ti,current-limit = <900000>; 62 ti,ovp-voltage = <9500000>; 63 ti,in-dpm-voltage = <4440000>; 64 };
