Binding for GPIO Gas Gauge
Required properties:
- compatible: "gpio-gas-gauge"
- gpios: GPIO which will change value to signal when the power is low and
the system should shutdown. This GPIO should include flags to
specify if the GPIO is active low or not. In this case, active low
would mean that the GPIO would go 0->1 when the power is low.
Optional properties:
- supply-name: This is a string which can be passed through to use as the
name of the power supply. It defaults to gpio-gas-gauge.
Example:
gpio-gas-gauge {
compatible = "gpio-gas-gauge";
gpios = <TEGRA_GPIO(D, 3) 0>;
supply-name = "GPIO_gas_gage";
status = "okay";
};
