This driver is implemented to parse the gps_en gpio from device tree
|
||
|
|
and create a sysfs to control the gpio in gpsd binary. Also it
|
||
|
|
registers a irq to enable the HW geofencing feature.
|
||
|
|
|
||
|
|
SYSFS: This interface is used to toggle gps_en gpio in userspace.
|
||
|
|
|
||
|
|
Required Properties:
|
||
|
|
- compatible: Must be "gps-wake";
|
||
|
|
- gps-enable-gpio is resource name for gpio which power ON gps
|
||
|
|
|
||
|
|
Optional Properties:
|
||
|
|
- gps-wakeup-gpio is resource name for gps host wake irq line
|
||
|
|
|
||
|
|
Example:
|
||
|
|
gps_wake {
|
||
|
|
compatible = "gps-wake";
|
||
|
|
id = <0>;
|
||
|
|
gps-enable-gpio = <&gpio_i2c_1_20 10 0>;
|
||
|
|
gps-wakeup-gpio = <&gpio TEGRA_GPIO(Q, 5) 0>;
|
||
|
|
status = "okay";
|
||
|
|
};
