Mediatek-based GNSS Receiver DT binding
|
|
Mediatek chipsets are used in GNSS-receiver modules produced by several
|
vendors and can use a UART interface.
|
|
Please see Documentation/devicetree/bindings/gnss/gnss.txt for generic
|
properties.
|
|
Required properties:
|
|
- compatible : Must be
|
|
"globaltop,pa6h"
|
|
- vcc-supply : Main voltage regulator (pin name: VCC)
|
|
Optional properties:
|
|
- current-speed : Default UART baud rate
|
- gnss-fix-gpios : GPIO used to determine device position fix state
|
(pin name: FIX, 3D_FIX)
|
- reset-gpios : GPIO used to reset the device (pin name: RESET, NRESET)
|
- timepulse-gpios : Time pulse GPIO (pin name: PPS1, 1PPS)
|
- vbackup-supply : Backup voltage regulator (pin name: VBAT, VBACKUP)
|
|
Example:
|
|
serial@1234 {
|
compatible = "ns16550a";
|
|
gnss {
|
compatible = "globaltop,pa6h";
|
vcc-supply = <&vcc_3v3>;
|
};
|
};
