Binding for SIRF GNSS receiver control driver
|
||
|
|
GPIO pins are toggled to control GNSS receiver power states either to
|
||
|
|
wake it from sleep or put receiver into sleep mode
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: must be "qcom,gnss_sirf"
|
||
|
|
- #gpio-pins:
|
||
|
|
0: GPIO 18
|
||
|
|
1: GPIO 87
|
||
|
|
|
||
|
|
Example:
|
||
|
|
ss5_pwr_ctrl0 {
|
||
|
|
compatible = "qcom,gnss_sirf";
|
||
|
|
pinctrl-0 = <&ss5_pwr_ctrl_rst_on>;
|
||
|
|
ssVreset-gpio = <&tlmm 87 1>;
|
||
|
|
ssVonoff-gpio = <&tlmm 18 1>;
|
||
|
|
};
|
||
|
|
|
||
|
|
ss5_pwr_ctrl_pins: ss5_pwr_ctrl_pins {
|
||
|
|
ss5_pwr_ctrl_rst_on: ss5_pwr_ctrl_rst_on {
|
||
|
|

||
|
