Subject: [PATCH 2/2] dt-bindings: display: sii902x: Add supply bindings
Date: Thu, 24 Sep 2020 15:05:06 -0500	[thread overview]
Message-ID: <20200924200507.1175888-2-mr.nuke.me@gmail.com> (raw)
In-Reply-To: <20200924200507.1175888-1-mr.nuke.me@gmail.com>

The sii902x chip family requires IO and core voltages to reach the
correct voltage before chip initialization. Add binding for describing
the two supplies.
