Thanks.

Unfortunately it did not reveal anything new :-(

I did few more changes to the Baytrail pinctrl driver which are now
included in linux-next. Can you try with the latest linux-next or
alternatively cherry-pick following commits on top of 4.0-rc3:

a485923efbb8 HID: i2c-hid: Add support for ACPI GPIO interrupts
6d00f37e49d9 HID: i2c-hid: Limit reads to wMaxInputLength bytes for input events
f2de746c3f03 HID: i2c-hid: The interrupt should be level sensitive
fcc18deb7682 pinctrl: baytrail: Save pin context over system sleep
31e4329f9906 pinctrl: baytrail: Rework interrupt handling
95f0972c7e4c pinctrl: baytrail: Clear interrupt triggering from pins that are in GPIO mode
f8323b6bb2cc pinctrl: baytrail: Relax GPIO request rules
