| ltc3651-charger |
| |
| 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>; |
| }; |
