[PATCH 1/2] dt-bindings: input: touchscreen: ti,tsc2005: Add wakeup-source

[phucduc.bui@gmail.com]

From: bui duc phuc <phucduc.bui@gmail.com>

The tsc200x driver uses the "wakeup-source" device tree property to
determine whether the device should be configured as a system wakeup
source.

In the driver, this property is read with:

    device_init_wakeup(dev,
                       device_property_read_bool(dev, "wakeup-source"));

Document this property in the binding to make it visible to DT schema
validation tools and to clarify its usage in device tree descriptions.
