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>;
};
};
