Goodix Touch driver integration failure

[aditya17]

Hi NXP Community,

I am trying to add the goodix predefined touchscreen driver with following configuration in the dts file of imx8mPlus:- 

&i2c5 {

    status = "okay";

    pinctrl-names = "default";

    pinctrl-0     = <&pinctrl_i2c5>;

clock-frequency = <200000>;

    goodix@14 {

        compatible        = "goodix,gt911";

        reg               = <0x14>;

        reset-gpios       = <&gpio5 10 GPIO_ACTIVE_LOW>;

        irq-gpios         = <&gpio4 19 IRQ_TYPE_EDGE_FALLING>;

        interrupt-parent  = <&gpio4>;

        interrupt-names   = "irq";

        pinctrl-names     = "default";

        pinctrl-0         = <&pinctrl_ts>;

        status            = "okay";

    };

};

&iomuxc {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_hog>;

pinctrl_i2c5: i2c5grp { /* I2C5: I2C5 IOMUX Pin Configuration */

fsl,pins = <

MX8MP_IOMUXC_SPDIF_RX__I2C5_SDA         0x400001c3

MX8MP_IOMUXC_SPDIF_TX__I2C5_SCL         0x400001c3

>;

};
pinctrl_ts: tsgrp {
fsl,pins = <
// 0x2, 0x00
MX8MP_IOMUXC_SAI1_TXD7__GPIO4_IO19 0x10b0b1 // IRQ pin (GT911 interrupt)
MX8MP_IOMUXC_ECSPI2_SCLK__GPIO5_IO10 0x1b0b1 // Reset pin (GT911 reset)
>;
};
};

 and the following in imx8mp_iwg40_gki.fragment

CONFIG_TOUCHSCREEN_GOODIX=m
CONFIG_I2C_CHARDEV=m

CONFIG_I2C=m

Upon boot , the module is not being attached by default

After attaching it manually , it shows the following error
