Then better to prepare for this now, otherwise later you need to change
bindings. If unsure what other variants are, then at least make this
compatible panel-specific, e.g. lenovo,yoga-slim7x-gen11-oled-foo-bar.

Adding fallback compatible is not usually incompatible ABI change, thus
you can always do it later if needed.
