Title: Sometimes touchpad automatically trigger double click Status in HWE Next: New Status in linux package in Ubuntu: Fix Committed Status in linux-oem-osp1 package in Ubuntu: Invalid Status in linux source package in Bionic: New Status in linux-oem-osp1 source package in Bionic: Fix Committed Status in linux source package in Disco: Fix Committed Status in linux-oem-osp1 source package in Disco: New Bug description: [Impact] Dell machines which uses goodix touchpad IC emit double click event while touching the touchpad if designware i2c adapter is in runtime suspend. Goodix re-assert the interrupt if host doesn't read the data within 100ms and designware takes a longer time to wake up from runtime suspend. In the case, it got a second interrupt during resuming, so it thinks it's a double click. [Fix] There is no simple way to fix this, it's a firmware issue and goodix agrees to fix this in their firmware on next release, but this issue is still affects the machines that don't come with an updated firmware. So, add a quirk to mark those machines and avoid the designware from entering runtime suspend. [Regression Potential] Low, it only affects the listed machines, and prevent designware from entering runtime suspend impacts the power consumption little or none during short or long idle.
