This issue doesn't happen on Windows. Comparing the GPIO register configuration between Windows and Linux bit 20 has been configured as a pull up on Windows, but not on Linux. Checking GPIO declaration from the firmware it is clear it *should* have been a pull up on Linux as well. ``` GpioInt (Level, ActiveLow, Exclusive, PullUp, 0x0000, "\\_SB.GPIO", 0x00, ResourceConsumer, ,) { // Pin list 0x0007 } ``` On Linux amd_gpio_set_config() is currently only used for programming the debounce. Actually the GPIO core calls it with all the arguments that are supported by a GPIO, pinctrl-amd just responds `-ENOTSUPP`. To solve this issue expand amd_gpio_set_config() to support the other arguments amd_pinconf_set() supports, namely `PIN_CONFIG_BIAS_PULL_DOWN`, `PIN_CONFIG_BIAS_PULL_UP`, and `PIN_CONFIG_DRIVE_STRENGTH`.
