lynxpoint: Add an inverted input GPIO type
The wake device input pins are active low and the
GPIOs need to be set as inverted when they are marked
as an input so they are not spuriously logged.
suspend/resume on slippy with trackpad wake:
8 | 2013-05-29 07:43:14 | ACPI Enter | S3
9 | 2013-05-29 07:43:18 | ACPI Wake | S3
10 | 2013-05-29 07:43:18 | Wake Source | GPIO | 12
and with power button wake:
11 | 2013-05-29 07:43:35 | ACPI Enter | S3
12 | 2013-05-29 07:43:40 | EC Event | Power Button
13 | 2013-05-29 07:43:40 | ACPI Wake | S3
14 | 2013-05-29 07:43:40 | Wake Source | Power Button | 0
