Subject: [PATCH v2 3/6] dt-bindings: hwlock: update STM32 #hwlock-cells value
Date: Thu, 25 Apr 2019 11:17:20 +0200	[thread overview]
Message-ID: <1556183843-28033-4-git-send-email-fabien.dessenne@st.com> (raw)
In-Reply-To: <1556183843-28033-1-git-send-email-fabien.dessenne@st.com>

Use a value of 2, so users can share hwlocks.
