How do I discover the ACPI id for a laptop touchpad in Linux?

How do I get the device ID for my touchpad in Linux? The device doesn't show up in lspci, lsusb, or cat /proc/bus/input/devices. For example, this patch adds the ID "ELAN0608": https://lkml.org/lkml/2017/8/10/145

I have a similar touchpad but I'm not sure what the ID is - it may need a change in the kernel. How do kernel developers go about querying info like this?
