Subject: [PATCH v4 2/4] dt-bindings: gnss: add mediatek binding
Date: Wed, 13 Feb 2019 16:09:27 +0100 [thread overview]
Message-ID: <1550070569-18588-3-git-send-email-lollivier@baylibre.com> (raw)
In-Reply-To: <1550070569-18588-1-git-send-email-lollivier@baylibre.com>
Add binding for Mediatek-based GNSS receivers.
Signed-off-by: Loys Ollivier <lollivier@baylibre.com>
---
v4:
Use standard names for reset-gpios and gnss-fix-gpios
s/an/a UART
v3:
Removed the I2C and SPI interfaces references.
Removed the "mediatek,mt3339" compatible line.
Added the optional propertied (reset, fix)
Added the pin names for the optional properties.
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 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)
+- v-bckp-supply : Backup voltage regulator
+ (pin name: VBAT, VBACKUP)
+
+Example:
+
+serial@1234 {
+ compatible = "ns16550a";
+
+ gnss {
+ compatible = "globaltop,pa6h";
+ vcc-supply = <&vcc_3v3>;
+ };
+};
