[PATCH v6 2/2] dt-bindings: mfd: update TI tps6105x chip bindings
From: Sven Van Asbroeck
Date: Mon Dec 16 2019 - 09:33:12 EST
The driver has been extended to optionally get its operational
mode, regulator init data and LED naming from the devicetree.

-Example:
+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.
