设备树路径为OK8MP-linux-sdk/OK8MP-linux-kernel/arch/arm64/boot/dts/freescale/OK8MP-C.dts在i2c3节点下加入TSC2007节点：

touchscreen: tsc2007@48 {

  compatible = "ti,tsc2007";

  reg = <0x48>;

  pinctrl-names = "default";

  pinctrl-0 = <&pinctrl_i2c4_gt928_io>;

  interrupt-parent = <&gpio1>;

  interrupts = <0 IRQ_TYPE_EDGE_FALLING>;

  gpios = <&gpio1 0 GPIO_ACTIVE_LOW>;

  ti,x-plate-ohms = <660>;

  ti,max-rt =<2000>;

  linux,wakeup;

  status = "okay";

};

修改OK8MP-C_defconfig加入TSC2007驱动编译
