Title:
[linux-oem] Use I2C transport for touchpad on Precision M5530
Status in HWE Next:
New
Status in linux package in Ubuntu:
Incomplete
Bug description:
=== SRU Justification ===
[Impact]
Touchpad on Precision M5530 uses PS/2 instead of I2C as its transport.
[Test Case]
The touchpad binds to psmouse instead of i2c_hid.
With the patch, the touchpad uses i2c_hid instead.
[Fix]
LKML Link: https://lkml.org/lkml/2018/1/30/963
The de facto standard, Windows, parse its DSDT as a term list. The DSDT
table on Precision M5530 also designed that way, hence we should just
respect that.
Add a new quirk for this specific machine.
I'll backport the patch for stable releases once it's upstreamed.
[Regression Potential]
Low. This fix is limited to XPS 15 9570/Precision M5530. Also it's the
"correct" way to do for this machine.
