touchpad not working on lenovo yoga 530

Bug description:
=== SRU Justification ===
[Impact]
AMD MP2 I2C driver doesn't support more than one bus.
This makes touchpad on Lenovo Yoga 530 doensn't work as expected.
[Fix]
Sync the MP2 driver with upstream version.
[Test]
The new upstream driver doesn't break on Latitude 5495.
Users haven't given any feedback yet, but since Disco is freezing I
am sending this out.
[Regression Potential]
Low. It's from upstream, and only a subset of Raven Ridge has this
device.
=== Original Bug Report ===
The touchpad is not working and does not show up in cat
/proc/bus/input/devices on multiple kernels. I've tried the newest
kernel to date (19.08.18) and a few others.
The touchpad works on windows.
