* 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;
|
|
