Subject: [PATCH v3 2/6] dt-bindings: power: supply: Extend max17040 compatibility
Date: Wed, 24 Jun 2020 18:56:29 +0300	[thread overview]
Message-ID: <20200624155633.3557401-3-iskren.chernev@gmail.com> (raw)
In-Reply-To: <20200624155633.3557401-1-iskren.chernev@gmail.com>

Maxim max17040 is a fuel gauge from a larger family utilising the Model
Gauge technology. Document all different compatible strings that the
max17040 driver recognizes.

Some devices in the wild report double the capacity. The
maxim,double-soc (from State-Of-Charge) property fixes that.
