Required properties:
|
||
|
|
- compatible: "lltc,ltc3651-charger"
|
||
|
|
- lltc,acpr-gpios: Connect to ACPR output. 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 ltc3651 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,ltc3651-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>;
|
||
|
|
};
