Subject: [PATCH] platform/chrome: chromeos_tbmc : Report wake events.
Date:   Fri, 30 Aug 2019 16:14:04 -0700

Mark chromeos_tbmc as wake capable and report wake events. This helps to
abort suspend on seeing a tablet mode switch event when kernel is
suspending. This also helps identifying if chroemos_tbmc is the wake
source.
