Signed-off-by: Loys Ollivier --- 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. .../devicetree/bindings/gnss/mediatek.txt | 37 ++++++++++++++++++++++ 1 file changed, 37 insertions(+) create mode 100644 Documentation/devicetree/bindings/gnss/mediatek.txt diff --git a/Documentation/devicetree/bindings/gnss/mediatek.txt b/Documentation/devicetree/bindings/gnss/mediatek.txt new file mode 100644 index 000000000000..00650d81c5c8 --- /dev/null +++ b/Documentation/devicetree/bindings/gnss/mediatek.txt @@ -0,0 +1,37 @@ +Mediatek-based GNSS Receiver DT binding + +Mediatek chipsets are used in GNSS-receiver modules produced by several +vendors and can use an 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: + +- gtop,reset-gpios : GPIO used to reset the device + (pin name: RESET, NRESET) +- gtop,fix-gpios : GPIO used to determine device position fix state + (pin name: FIX, 3D_FIX) +- timepulse-gpios : Time pulse GPIO (pin name: PPS1, 1PPS) +- v-bckp-supply : Backup voltage regulator + (pin name: VBAT, VBACKUP) +- current-speed : Default UART baud rate + +Example: + +serial@1234 { + compatible = "ns16550a"; + + gnss { + compatible = "globaltop,pa6h"; + vcc-supply = <&vcc_3v3>; + }; +}; -- 2.7.4
