0bb7b9860f hwdb: add a 70-touchpad.hwdb to tag internal vs external touchpads
Add a new key ID_INPUT_TOUCHPAD_INTEGRATION=internal|external so we have a
single source for figuring out which touchpads are built-in.

Fairly simple approach: bluetooth is external, usb is external unless it's an
Apple touchpad. Everything else is internal.

0530459245 Revert "hwdb: add a touchpad hwdb"
The main purpose of this hwdb was to tag touchpads that have the physical
trackstick buttons wired to the touchpad (Lenovo Carbon X1 3rd, Lenovo *50
series).  This hwdb is not required on kernels 4.0 and above, the kernel now
re-routes button presses through the trackstick's device node. Userspace does
not need to do anything.

See kernel commit cdd9dc195916ef5644cfac079094c3c1d1616e4c.

This reverts commit 001a247324.

001a247324 hwdb: add a touchpad hwdb
Currently used to tag devices in the new Lenovo *50 series and the X1 Carbon
3rd. These laptops re-introduced the physical trackpoint buttons that were
missing from the *40 series but those buttons are now wired up to the
touchpad.

The touchpad now sends BTN_0, BTN_1 and BTN_2 for the trackpoint. The same
button codes were used in older touchpads that had dedicated scroll up/down
buttons. Input drivers need to work around this and thus know what they're
dealing with.

For the previous gen we introduced INPUT_PROP_TOPBUTTONPAD in the kernel, but
the resulting mess showed that these per-device quirks should really live in
userspace.

The list currently includes the X1 Carbon 3rd PNPID, others will be added as
get to know which PNPID they have.
