So are you seeing these 7 interrupts / second for the touchpad irq or for
the GPIO controllers parent irq ?
Also to these 7 interrupts/sec stop happening when you do not touch the
touchpad ?
I see these 7 interrupts / second for the GPIO controller's parent irq.
And they stop happening when I don't touch the touchpad.
Only from the parent irq, or also on the touchpad irq itself ?
If this only happens on the parent irq, then I would start looking at the
amd-pinctrl code which determines which of its "child" irqs to fire.
This only happens on the parent irq. The input's pin#130 of the GIPO
chip is low most of the time and pin#130.
Right, but it is a low-level triggered IRQ, so when it is low it should
be executing the i2c-hid interrupt-handler. If it is not executing that
then it is time to look at amd-pinctrl's irq-handler and figure out why
that is not triggering the child irq handler for the touchpad.
