1. Copy lsm6ds3 to kernel/drivers/input/sensors/ directory.
2. Modify the kernel/drivers/input/sensors/Kconfig as follows

source "drivers/video/lsm6ds3/Kconfig"

3. Modify the kernel/drivers/input/sensors/Makefile as follows

obj-$(CONFIG_INPUT_LSM6DS3) += lsm6ds3/

4. Modify the dts as follows

&i2c2 {
	status = "okay";
	
	lsm6ds3@6b {
		compatible = "st,lsm6ds3";
		reg = <0x6b>;
		st,irq_gpio = <&gpio1 GPIO_A3 GPIO_ACTIVE_LOW>;

		st,drdy-int-pin = <1>;
		
		// 0: xyz 1:xzy 2:yxz 3:yzx 4:zxy 5:zyx
		st,xyz = <2>;
		st,x-reverse = <1>;
		st,y-reverse = <1>;
		st,z-reverse = <0>;
	};
};

Android HAL, please refer to the file modification in the hardware.
