Subject: [PATCH v4 2/2] dt-bindings: mfd: update TI tps6105x chip bindings
Date:   Thu, 21 Nov 2019 09:27:26 -0500
Message-Id: <20191121142726.22856-3-TheSven73@gmail.com>

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The driver has been extended to optionally get its operational
mode, regulator init data and led naming from the devicetree.

+Optional sub-node:
+
+This subnode selects the chip's operational mode.
+There can be at most one single available subnode.

+- regulator: presence of this sub-node puts the chip in regulator mode.
