Subject: [PATCH v3 1/2] Documentation: devicetree: update bindings for tps23861
The tps23861 driver does not initialize the chip and relies on it being
in auto-mode by default. On some devices, these controllers default to
OFF-Mode and hence cannot be used at all.
This brings minimal support for initializing the controller in a user-
defined mode.
