| description: | |
| AK8975 has a "Data ready" pin (DRDY) which informs that data |
| is ready to be read and is possible to listen on it. If used, |
| this should be active high. Prefer interrupt over this. |

| interrupts: |
| maxItems: 1 |
| description: interrupt for DRDY pin. Triggered on rising edge. |
| |
| vdd-supply: |
| description: | |
| an optional regulator that needs to be on to provide VDD power to |
| the sensor. |
| |
| mount-matrix: |
| description: an optional 3x3 mounting rotation matrix. |
