This driver maps the Lenovo Yoga tablet mode switch to a SW_TABLET_MODE input device. This will make the tablet status available to desktop environments. This patch series is the result of the discussion at https://lore.kernel.org/r/CAG4kvq9US=-NjyXFMzJYu2zCJryJWtOc7FGZbrewpgCDjdAkbg@xxxxxxxxxxxxxx/ I decided to follow-up on the patch Gergo wrote and respond to the review comments to get it merged and available for everyone. As Gergo said: It should work with models like the Yoga C940, Ideapad flex 14API, Yoga 9 14IAP7, Yoga 7 14ARB7. The 14ARB7 model must trigger the EC to send mode change events. This might be a firmware bug. I have additionally tested this on the Yoga 7 14IAL7.
