&pio {
        twi0_pins_c: twi0@0 {
                pins = "PG12", "PG13";  /*sck sda*/
                function = "twi0";
                muxsel = <3>;
                drive-strength = <10>;
        };

        twi0_pins_d: twi0@1 {
                pins = "PG12", "PG13";
                function = "gpio_in";
        };
}

&twi0 {
        clock-frequency = <400000>;
        pinctrl-0 = <&twi0_pins_c>;
        pinctrl-1 = <&twi0_pins_d>;
        pinctrl-names = "default", "sleep";
        status = "okay";

        tsc2007@48 {
                compatible = "ti,tsc2007";
                reg = <0x48>;
                interrupt-parent = <&pio>;
                interrupts = <PB 2 IRQ_TYPE_EDGE_FALLING>;
                ti,x-plate-ohms = <400>;
        };
};

kernel 配置勾选 tsc2007，然后用 evtest 测试电阻触摸屏，一切OK了。
