Subject: [PATCH v2 1/4] dt-bindings: mrvl,mmp-timer: add clock
Date: Tue, 18 Sep 2018 22:54:52 +0200 [thread overview]
Message-ID: <20180918205455.25464-2-lkundrak@v3.sk> (raw)
In-Reply-To: <20180918205455.25464-1-lkundrak@v3.sk>
The timer needs the timer clock to be enabled, otherwise it stops
ticking.
Signed-off-by: Lubomir Rintel <lkundrak@v3.sk>

Changes since v1:
- Made the clock optional, to keep compatibility with DTs without it
