@Subrata, Yes. this issue is found while we are enabling touchscreen and touchpad wake, where the wake is specified using GpioInt in the _CRS method. The specified ACPI GPIO number in GpioInt is used to map to the PAD in corresponding pinctrl instance. Note that for those _CRS methods that use Interrupt descriptor, such as touchscreen/touchpad in LPSS-i2c mode, are not impacted as the interrupt number is used directly and does not need to find out from any of the pinctrl instances.
