Like with the GPIO mouse input, I found that this driver has no in-tree users at all.
I *could* just propose to delete it. But the driver seems generally useful, so I made a patch series shaping it up to get configuration from device tree or ACPI DSDT using device properties instead. We start off the series by defining a set of device tree bindings for it. It would be great to have some input from the initial authors on this rewrite. I think we would not merge any board file using the platform data anymore, so making it an all-in device property (device tree || ACPI) driver seems reasonable.
