1 Binding for TI bq24250/bq24251/bq24257 Li-Ion Charger
4 - compatible: Should contain one of the following:
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).
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
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
