This rewrites the Mediatek GNSS bindings in YAML.

Cc: Krzysztof Kozlowski <krzk@kernel.org>
Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

ChangeLog v1->v2:
- New patch since Krzysztof pointed out there is really just
one more binding to convert, so why not.

-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>;
- };
-};
