We have received feedback in our forum that the touchpad no longer works
after a resuming from suspend.
I've attached the link - maybe you can take a look at it.

Additional notes to #211:
Actually rebooting your machine is not necessary for simply testing the
module. You can remove the old kernel first,

and then insert the new module with the parameter "polling_mode=1"
$ sudo insmod i2c-hid.ko polling_mode=1

Thank you for sharing the results and investigating this touchpad issue!
One thing confuses me is for the ELAN touchpad, no single interrupt
fires when you put finger on the touchpad while for the Synaptics
touchpad, you still see interrupts firing but with a very rate of ~7Hz.
Judging

int pin_config;

int triggering;
unsigned int quirks;
};
enum gpiod_flags {
GPIOD_ASIS = 0,
GPIOD_IN=
according to the above analysis, error is happen with the direction is :
in
i found the function to set the direction of gpio pin to in:
amd_gpio_direction_input,
and add some pr_err and dump_stack() to the function ,
then dmesg out put like :
[1.545190] amd_gpio_set_config
i have already added some pr_err to the kernel source ,
then the dmesg say : the touchpad work 1 time,during the system boot.
the dmesg output like :
```
[1.766437] in handle_fasteoi_irq for irq:7,starting...
[1.766440] in handle_irq_event start for :7

so may be there is some bug with the :direction,
because ,i run echo out > direction,then it start to work.

I can't say why it hasn't been included in the kernel so far.
Here is the patch:
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-
Today I find something interesting about the GPIO controller. I wonder
if the same thing would happen to the ELAN touchpads.
For those who have the ELAN touchpad, could you show me the result of
the following experiment with a kernel not having the
polling_pin_state_touchpad.patch?
```bash

Thank you for testing this patch! I'm glad it also works for both
04F3:3140 and 04F3:3186. I was completely new to things like I2C, HID
before investigating this touchpad issue. So thank you for your patience
with me.
Note this patch is meant to be a temporary specifically for this laptop.
It
found a patch related to amd and gpio:
gpio: amd-fch: correct logic of GPIO_LINE_DIRECTION
The original commit appears to have the logic reversed in
amd_fch_gpio_get_direction. Also confirmed by observing the value of
"direction" in the sys tree.
Maybe expert could update in kernel git

I have not (yet) experienced the issue you are describing, or any issues
for that matter. Maybe you can remove and re-insert i2c_hid when this
happens? Hopefully a fix of the GPIO driver is not too far off and will
resolve the stability issues you are experiencing.

thanks @Mike Boruta (maridius)!
wondered why it worked after re-install of nvidia driver, so thats the
explanation now ;)
what about any issues with the touchpad?
not sure if something else produces my issues, but during longer usage there
random stutterings, the mouse is not moved for some

Wow, thanks a lot Coiby Xu! I applied the patch and the touchpad
04F3:3186 works as expected on the 5.7.19 ubuntu mainline kernel. Please
let me know if you need help developing/testing the final fix to
pinctrl_amd/amd_gpio.

@Coiby Xu, @wangjun, Helmut (schinfo) thank you for saving the day.
I've `git cloned` 5.8.12-3 Manjaro kernel from GitLab and using this
post I installed it on my system. -> https://forum.manjaro.org/t/how-to-
compile-patch-kernel-with-custom-alsa-driver/20326/4
Everything works like a charm
@Coiby YOU ARE THE MAN!
works like a charm on kernel 5.8.12-AMD!
thank you so much for your efforts. you should get paid by Lenovo for this ;)

Hey guys! Very excited and waited so much to the moment when this bug will be
fixed.
Any chances that the patch will be included into ubuntu mainline kernel build?
(something go wrong when I attempting to boot from the patched kernel: in the
very start says "Loading initial ramdisk" and hangs
... but:
have to modprobe -r and modprobe i2c_hid again, to get the touchpad working.
any ideas?
