thunderbolt: Add wake on connect/disconnect on USB4 ports
Wake on connect/disconnect is only supported while runtime suspend for now, which is obviously necessary. It is also not inherently desired for the system to wakeup on Thunderbolt/USB4 hot plug events. However, we can still make user in control of waking up the system in the events of hot plug/unplug. This patch adds 'wakeup' attribute under 'usb4_portX/power' sysfs attribute and only enables wakes on connect/disconnect to the respective port when 'wakeup' is set to 'enabled'. The attribute is set to 'disabled' by default. Signed-off-by: Rajat Khandelwal <rajat.khandelwal@intel.com> Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com>
