dts配置：
首先要确保CONFIG_I2C_HID宏打开，i2c-hid-core.c 文件才能编译进去代码。规格书vendor product 分别为0x2d1f 和0x0165 来区别，不至于影响到整体的hid其他设备。

   +  i2c-hid-dev@10 {+  compatible = "hid-over-i2c";+	reg = <0x10>;+	hid-descr-addr = <0x0001>;+	interrupt-parent = <&gpio0>;+	interrupts = <6 0x0>;+	post-power-on-delay-ms = <70>;+	vdd = "vdd-supply";+	status ="okay";+ };

hid-input.c 文件里面根据实际情况，是否实际需要x,y坐标是否需要反，或x , 或y 反，或x,y都反。
hidinput_configure_usage函数。这里面x,y需要对调，而且x，还需要最大变最小，最小变最大逻辑 20320-value
