dt-bindings:iio:pressure:meas,ms5611 yaml conversion. 



One addition here was to put in a 20MHz maximum for the SPI bus
as specified in the datasheets of both support parts.

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>;

};
