+MEAS ms5611 family pressure sensors
+
+Pressure sensors from MEAS Switzerland with SPI and I2C bus interfaces.
+
+Required properties:
+- compatible: "meas,ms5611" or "meas,ms5607"
+- reg: the I2C address or SPI chip select the device will respond to
+
+Optional properties:
+- vdd-supply: an optional regulator that needs to be on to provide VDD
+ power to the sensor.
+
+Example:
+
+ms5607@77 {
+ compatible = "meas,ms5607";
+ reg = <0x77>;
+ vdd-supply = <&ldo_3v3_gnss>;
+};
