Currently all ARM kernels will have s2idle enabled if CONFIG_SUSPEND is present. In this case if the lid is closed, systemd-logind will enter s2idle mode by default; however there's no possible wakeup source defined, so the system will enter a forever idle. Add the lid itself as a wakeup source, thus the system can wakeup when the lid is opened.
