When referencing other schema, it is preferred to use an absolute path
(/schemas/....), which allows also an seamless move of particular schema
out of Linux kernel to dtschema.

Extend the common binding to include a new variant of the silicon,
which effectively replaces a pair of slider nodes with a trackpad
node comprising the same or similar properties.
As part of this change, the if/then/else schema have been updated
to identify properties that are not supported by the new device.

The units assumed by the 'azoteq,top-speed', 'azoteq,bottom-speed'
and 'azoteq,gesture-dist' properties are unspecified; define them
according to the device's datasheet.

IQS7222A revisions 1.13 and later widen the gesture multiplier from
x4 ms to x16 ms; update the binding accordingly.
As part of this change, refresh the corresponding properties in the
example as well.

The minimum slider size enforced by the driver is 1 or 16 for the
IQS7222C or IQS7222A, respectively.

Following a recent refactor of the driver to properly drop unused
device nodes, the 'linux,code' property is now optional. This can
be useful for applications that define GPIO-mapped events that do
not correspond to any keycode.

Multiple bindings use 'linux,input-type', but there is not a central
definition and type. Add 'linux,input-type' to input.yaml and update all
the users to use it.

Although the IQS7222C does not offer slider gesture support, the
press/release event can still be mapped to any of the IQS7222C's
three GPIO pins. Update the binding to reflect this relationship.
