Subject: [PATCH 10/10] input: iqs5xx: Allow device to be a wake-up source
Date: Mon, 18 Jan 2021 14:43:46 -0600	[thread overview]
Message-ID: <1611002626-5889-11-git-send-email-jeff@labundy.com> (raw)
In-Reply-To: <1611002626-5889-1-git-send-email-jeff@labundy.com>

Avoid placing the device in suspend mode (from which it cannot
generate interrupts) if it is defined as a wake-up source. The
device is still permitted to enter a low-power sensing mode on
its own.
