亲们，请教一下，电容触摸（ GT911 ）的配置流程是什么？哪位有详细教程，多谢……

参考哪吒的SDK:

board.dts配置:

&twi2 {
        clock-frequency = <400000>;
        pinctrl-0 = <&twi2_pins_a>;
        pinctrl-1 = <&twi2_pins_b>;
        pinctrl-names = "default", "sleep";
        dmas = <&dma 45>, <&dma 45>;
        dma-names = "tx", "rx";
        status = "okay";


        ctp@14 {
                compatible = "allwinner,goodix";
                device_type = "ctp";
                reg = <0x14>;
                status = "okay";
                ctp_name = "gt9xxnew_ts";
                ctp_twi_id = <0x2>;
                ctp_twi_addr = <0x14>;
                ctp_screen_max_x = <0x320>;
                ctp_screen_max_y = <0x500>;
                ctp_revert_x_flag = <0x0>;
                ctp_revert_y_flag = <0x1>;
                ctp_exchange_x_y_flag = <0x0>;
                ctp_int_port = <&pio PG 14 GPIO_ACTIVE_HIGH>;
                ctp_wakeup = <&pio PG 15 GPIO_ACTIVE_HIGH>;
        };
};

驱动开启以下选项:

CONFIG_TOUCHSCREEN_GT9XXNEW_TS
CONFIG_TOUCHSCREEN_GT9XXNEWDUP_TS
