See remark below. + +Optional properties: + - lltc,fault-gpios: Connect to FAULT output. See remark below. + - lltc,chrg-gpios: Connect to CHRG output. See remark below. + +The lt3651 outputs are open-drain type and active low. The driver assumes the +GPIO reports "active" when the output is asserted, so if the pins have been +connected directly, the GPIO flags should be set to active low also. + +The driver will attempt to aquire interrupts for all GPIOs to detect changes in +line state. If the system is not capabale of providing interrupts, the driver +cannot report changes and userspace will need to periodically read the sysfs +attributes to detect changes. + +Example: + + charger: battery-charger { + compatible = "lltc,lt3651-charger"; + lltc,acpr-gpios = <&gpio0 68 GPIO_ACTIVE_LOW>; + lltc,fault-gpios = <&gpio0 64 GPIO_ACTIVE_LOW>; + lltc,chrg-gpios = <&gpio0 63 GPIO_ACTIVE_LOW>; + }; |
