Title:
Backport support for ACPI GPIO interrupts for i2c-hid devices
Status in HWE Next:
New
Status in linux package in Ubuntu:
Triaged
Status in linux source package in Vivid:
Fix Released
Bug description:
[Impact]
On some platforms HID over I2C uses GPIO interrupts instead of
directly connected to the IO-APIC. Without ACPI GPIO interrupts
support, i2c-hid can not find IRQ when probing the device, and shows
the following message:
i2c_hid i2c-SYNA7508:00: Could not register for SYNA7508:00 interrupt, irq =
-1, ret = -22
i2c_hid: probe of i2c-SYNA7508:00 failed with error -22
So far we've found this issue on some SKL platforms, and one BSW
platform.
[Fix]
There's a fix in mainline v4.1-rc1, which add the support for ACPI
GPIO interrupts for i2c-hid module.
Commit log is as follows:

HID: i2c-hid: Add support for ACPI GPIO interrupts
[Test]
1. Boot with 4.1-rc1 kernel and patched 3.19 kernel
2. Both touchscreen should work
