Only use one method. - 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,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 a USB D+/D- signal based charger + type detection is used (if available) and the input limit current is set + accordingly. If the D+/D- based detection is not available on a given device + a default of 500,000 is used (=500mA). +- 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. +- ti,safety-timer-2x-enable: If this property is set to 1 the device's safety + timer is extended (slowed down) by a factor of two. Setting this property + to 0 or not providing it will leave the safety timer at its default + setting. +- interrupt-parent: Should be the phandle for the interrupt controller. Use in + conjunction with "interrupts" and only in case "stat-gpios" is not used. +- interrupts: Interrupt mapping for GPIO IRQ (configure for both edges).
