rk3399传感器调式mma8452 ak8963

ti

1,配置dts
在rk3399/RP/kernel/arch/arm64/boot/dts/rockchip/rp-rk3399.dts/文件下配置
mma8452@1d {
            status = "okay"; //status = "disabled";
            compatible = "fsl,mma8452";
            pinctrl-names = "default";
            pinctrl-0 = <&mma8452_irq_gpio>;
            reg = <0x1d>;
            irq-gpio = <&gpio0 12 IRQ_TYPE_EDGE_RISING>;//&gpio0 12
            type = ;
            irq_enable = <1>;
            poll_delay_ms = <30>;
            power-off-in-suspend = <1>;
            layout = <4>;
      };
sensor@0f {
            status = "okay"; //status = "disabled";
            compatible = "ak8963";
            pinctrl-names = "default";
            pinctrl-0 = <&ak8963_irq_gpio>;
            reg = <0x0f>;
            type = ;
            irq-gpio = <&gpio1 20 IRQ_TYPE_EDGE_RISING>;//&gpio1 20
            irq_enable = <1>;
            poll_delay_ms = <30>;
            layout = <3>;
      };
由于缺少头文件必须把#include 添加进去否则编译不过

2配置deconfig
在rk3399/RP/kernel/arch/arm64/configs/rockchip_defconfig下添加
+CONFIG_MMA8452=y
+CONFIG_AK8975=y

3,编译烧录
