KXTJ3-1057 加速度计传感器的 DTS 设备覆盖文件

Question

告诉我，设备树中有加速计吗？

&i2c3 {
    status = "okay";

    gs_kxtj3: gs_kxtj3@e {
        compatible = "gs_kxtj3";
        reg = <0x0e>;
        irq-gpio = <&gpio1 RK_PB0 IRQ_TYPE_EDGE_RISING>;
        irq_enable = <0>;
        poll_delay_ms = <30>;
        type = <SENSOR_TYPE_ACCEL>;
        layout = <0>;
        status = "okay";
    };

我对以下属性的含义感兴趣：

irq_enable = <0>;
poll_delay_ms = <30>;
layout = <0>;

Answer 1

这意味着 1、禁用irq 2、每隔30ms，驱动会读取设备的寄存器，并将数据上报给上层软件
