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.

Write your commit messages independent of the Linux driver.

Hi Rob,

> Write your commit messages independent of the Linux driver.

Thanks for the feedback.

I will rewrite the commit message to focus on the hardware description
and formalizing the binding, and remove references to the Linux driver
implementation.

I will send a v2 shortly with this change.

Best regards,
Phuc
