Hi,
In our custom AM3351 board, touch is not working. We have built the goodix as module and loaded into kernel. while loading we are getting messages as
[ 50.423448] Goodix-TS 0-0014: ID 928, version: 1040
[ 50.467240] Goodix-TS 0-0014: Invalid config, using defaults
[ 50.492693] input: Goodix Capacitive TouchScreen as /devices/platform/ocp/44e0b000.i2c/i2c-0/0-0014/input/input0
the device is getting created as
lrwxrwxrwx 1 root root 6 Jul 8 22:44 /dev/input/touchscreen0 -> event0
i have tried by checking cat /proc/interrupts, which is always coming as
182: 0 INTC 22 Level gt928
i have tried evtest /dev/input/touchscreen0, where the log is coming as
Input driver version is 1.0.1

We are suspecting that interrupts are not coming from the device. But we are not sure on that. Can some one tell me the problem here and help to solve this.
the dts configuration is as follows,
gt928@14 {
compatible = "goodix,gt928";
reg = <0x14>;
interrupt-parent = <&clkout2_pin>;/
interrupts = <22 1>;
goodix,rst-gpio = <&ts_reset_pin_default>;
goodix,irq-gpio = <&ts_int_pin_default>;
