| BMP085/BMP18x/BMP28x digital pressure sensors |
| |
| Required properties: |
| - compatible: must be one of: |
| "bosch,bmp085" |
| "bosch,bmp180" |
| "bosch,bmp280" |
| "bosch,bme280" |
| |
| Optional properties: |
| - chip-id: configurable chip id for non-default chip revisions |
| - temp-measurement-period: temperature measurement period (milliseconds) |
| - default-oversampling: default oversampling value to be used at startup, |
| value range is 0-3 with rising sensitivity. |
| - interrupt-parent: should be the phandle for the interrupt controller |
| - interrupts: interrupt mapping for IRQ |
| - reset-gpios: a GPIO line handling reset of the sensor: as the line is |
| active low, it should be marked GPIO_ACTIVE_LOW (see gpio/gpio.txt) |
| - vddd-supply: digital voltage regulator (see regulator/regulator.txt) |
| - vdda-supply: analog voltage regulator (see regulator/regulator.txt) |
| |
| Example: |
| |
| pressure@77 { |
| compatible = "bosch,bmp085"; |
| reg = <0x77>; |
| chip-id = <10>; |
| temp-measurement-period = <100>; |
| default-oversampling = <2>; |
| interrupt-parent = <&gpio0>; |
| interrupts = <25 IRQ_TYPE_EDGE_RISING>; |
| reset-gpios = <&gpio0 26 GPIO_ACTIVE_LOW>; |
| vddd-supply = <&foo>; |
| vdda-supply = <&bar>; |
| }; |
