Murata ZPA2326 pressure sensor



Pressure sensor from Murata with SPI and I2C bus interfaces.



Required properties:

- compatible: "murata,zpa2326"

- reg: the I2C address or SPI chip select the device will respond to



Recommended properties for SPI bus usage:

- spi-max-frequency: maximum SPI bus frequency as documented in

  Documentation/devicetree/bindings/spi/spi-bus.txt



Optional properties:

- vref-supply: an optional regulator that needs to be on to provide VREF

  power to the sensor

- vdd-supply: an optional regulator that needs to be on to provide VDD

  power to the sensor

- interrupt-parent: phandle to the parent interrupt controller as documented in

  Documentation/devicetree/bindings/interrupt-controller/interrupts.txt

- interrupts: interrupt mapping for IRQ as documented in

  Documentation/devicetree/bindings/interrupt-controller/interrupts.txt



Example:



zpa2326@5c {

	compatible = "murata,zpa2326";

	reg = <0x5c>;

	interrupt-parent = <&gpio>;

	interrupts = <12>;

	vdd-supply = <&ldo_1v8_gnss>;

};
