Add binding for Mediatek-based GNSS receivers.
Signed-off-by: Loys Ollivier <lollivier@xxxxxxxxxxxx>
---
v2:
Renamed bindings from Globaltop/gtop to Mediatek/mtk.
Moved current-speed as an optional propertie.
Removed the status line in the example.
Added "mediatek,mt3339" compatible.

+Mediatek-based GNSS Receiver DT binding
+
+Mediatek chipsets are used in GNSS-receiver modules produced by several
+vendors and can use UART, SPI or I2C interfaces.
+
+Please see Documentation/devicetree/bindings/gnss/gnss.txt for generic
+properties.
+
+Required properties:
+
+- compatible : Must be one of
+
+ "globaltop,pa6h"
+ "mediatek,mt3339"
+
+- vcc-supply : Main voltage regulator (pin name: 3V3_IN, VCC, VDD)
+
+Required properties (I2C):
+- reg : I2C slave address
+
+Required properties (SPI):
+- reg : SPI chip select address
+
+Optional properties:
+
+- timepulse-gpios : Time pulse GPIO
+- v-bckp-supply : Backup voltage regulator
+- current-speed : Default UART baud rate
+
+Example:
+
+serial@1234 {
+ compatible = "ns16550a";
+
+ gnss {
+ compatible = "globaltop,pa6h";
+ vcc-supply = <&vcc_3v3>;
+ };
+};
