Subject: [PATCH 2/2] arm64: allwinner: a64: allow laptops to wake up from lid
Date: Sat, 23 Jun 2018 00:06:31 +0800 [thread overview]
Message-ID: <20180622160631.8578-2-icenowy@aosc.io> (raw)
In-Reply-To: <20180622160631.8578-1-icenowy@aosc.io>
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.
