Subject: [PATCH 04/13] dt-bindings: power: supply: document Samsung S2M
 series PMIC charger device

Certain Samsung S2M series PMICs have a battery charger device which,
among other things, manages power interfacing of the USB port. It may
supply power, as done in USB OTG operation mode, or it may accept power
and redirect it to the battery fuelgauge for charging.

This driver depends on the MUIC device present in the same PMIC block.

The initial driver introduced has support for S2MU005, add its
compatible as well.
