From: Mario Limonciello <mario.limonciello@xxxxxxx> Some platforms include a human presence detection (HPD) sensor. When enabled and a user is detected a wake event will be emitted from the sensor fusion hub that software can react to. Example use cases are "wake from suspend on approach" or to "lock when leaving". This is currently enabled by default on supported systems, but users can't control it. This essentially means that wake on approach is enabled which is a really surprising behavior to users that don't expect it. Instead of defaulting to enabled add a sysfs knob that users can use to enable the feature if desirable and set it to disabled by default.
