Subject: [PATCH 5/9] mfd: sec: Enable wakeup from suspend via devicetree property
Date:   Tue, 20 Apr 2021 19:02:40 +0200
Message-Id: <20210420170244.13467-1-krzysztof.kozlowski@canonical.com>
In-Reply-To: <20210420170118.12788-1-krzysztof.kozlowski@canonical.com>

Set device wakeup capability from devicetree property (done by drivers
core), instead of always setting it to 0 (because value in platform data
is not assigned).

This should not have visible effect on actual resuming from suspend
because the child device - S5M RTC driver - is responsible for waking
up and sets device wakeup unconditionally.
