Subject: [PATCH v3 3/3] dt-bindings: display: sii902x: Add supply bindings
Date: Tue, 20 Oct 2020 17:14:59 -0500 [thread overview]
Message-ID: <20201020221501.260025-3-mr.nuke.me@gmail.com> (raw)
In-Reply-To: <20200928173056.1674274-1-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.
Signed-off-by: Alexandru Gagniuc <mr.nuke.me@gmail.com>
Acked-by: Rob Herring <robh@kernel.org>

Changes since v1, v2:
* Nothing. version incremented to stay in sync with sii902x regulator patch
* Added Rob's acked-by line
