Alternatively the pin can + also be defined through the standard interrupt definition properties (see + optional properties section below). Only use one method. +- pg-gpio: GPIO used for the device PG (Power Good) pin. This pin is not + available on all devices and therefore only required on applicable devices. + However it is also possible to explicitly disable the use of this pin + through the optional property "ti,pg-gpio-disable" (see below) if desired. + In this case the "pg-gpio" property is no longer required. - 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: +- ti,in-ilimit-autoset-disable: If this boolean property is present it disables + the automatic setting of the input current limit. This property is also set + implicitly on devices without charger type detection. If this property is + provided the input current limit should be set manually through + "ti,in-limit-current". +- ti,in-limit-current: The maximum current to be drawn from the charger's input + (in uA). Use this for devices that don't have charger type detection or if + you have have set "ti,in-ilimit-autoset-disable". +- ti,vovp-voltage: Configures the over voltage protection voltage (in uV). +- ti,vindpm-voltage: Configures the threshold input voltage for the dynamic + power path management (in uV). +- ti,pg-gpio-disable: If this boolean property is provided a software-based + approach for power good determination is used. Note that the PG-pin based + approach is generally preferable. +- ti,timer-2x-enable: If this boolean property is provided the device's safety + timer is extended by a factor of two. +- interrupt-parent: Should be the phandle for the interrupt controller. Use in + conjunction with "interrupts" and only in case "stat-gpio" is not used. +- interrupts: Interrupt mapping for GPIO IRQ (configure for both edges).
