== SRU Justification ==
[Impact]
Touchpad and touchscreen don't work on TGL-H laptops.
[Fix]
Update GPIO mapping so the values can match between Linux and BIOS.
[Test]
After applying the patch, both touchpad and touchscreen can work
correctly.
[Where problems could occur]
If somehow any of the new pin value is incorrect, it can break devices
that require Intel GPIO to work.
