Andan, Can you please test latest mainline kernel? I think this commit can fix your issue: commit 670784fb4ebe54434e263837390e358405031d9e Author: Kai-Heng Feng <kai.heng.f...@canonical.com> Date: Tue Apr 30 16:37:53 2019 +0800
pinctrl: intel: Clear interrupt status in mask/unmask callback Commit a939bb57cd47 ("pinctrl: intel: implement gpio_irq_enable") was added because clearing interrupt status bit is required to avoid unexpected behavior. Turns out the unmask callback also needs the fix, which can solve weird IRQ triggering issues on I2C touchpad ELAN1200.
