Wake-on-Touch (WoT) feature gives system the capability to wake from sleep state by user touch event, it requires platform providing wake GPIO through ACPI resource. Intel UEFI provides a user setting to enable or disable THC device WoT feature. If it's enabled, UEFI assigns an additional wake GPIO resource to THC device ACPI configuration, facilitating system wakeup. This patch provides helper APIs for THC device driver to query wake GPIO resource, enable WoT feature and unconfigure WoT. APIs added: - thc_wot_config(): Query and configure wake-on-touch feature. - thc_wot_unconfig(): Unconfig wake-on-touch feature.
