Ugh, this is exactly the kind of thing ACPI _DSD was intended to solve. Not a
lot we can do about the vendors not including the info in the DSDT of course,
but...  ugh.

I'm curious, are the vendors involved in driving these patches? If so, have you
asked them if they are aware of _DSD and if they would consider using it so they
can avoid having to patch the driver for every instance of a product using this
touchscreen?

Nope this is just a spare-time project of mine helping people who
want to run mainline Linux on various Bay Trail and Cherry Trail devices.

Just noticed LKML not Cc'd. Please Cc LKML on all patches to the Linux kernel.
