* Sensor Controller
Required properties:
- compatible: the sensor name,exampel: "gs_mma8452";
- reg: i2c slave address;
- type: sensor type;
- irq-gpio: sensor interrupt gpio pin;
- irq_enable: 1 use irq; 0 use pull mode;
- poll_delay_ms: pull delay time if use pull mode;
- layout: sensor orientation, choose 1-8 to make product work fine;
Example:
hall_sensor: hall-mh248 {
compatible = "hall-mh248";
pinctrl-names = "default";
pinctrl-0 = <&mh248_irq_gpio>;
irq-gpio = <&gpio1 2 IRQ_TYPE_EDGE_RISING>;
hall-active = <1>;
status = "okay";
};
sensor@1d {
compatible = "gs_mma8452";
