[PATCH v2 2/3] dt-bindings: hwmon: ti,ina2xx: Add ti,shunt-gain property

From: Nathan Rossi <hidden>
Date: 2021-10-27 07:42:46
Also in: linux-devicetree, lkml
Subsystem: hardware monitoring, open firmware and flattened device tree bindings, the rest · Maintainers: Guenter Roeck, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds

From: Nathan Rossi <redacted>

Add a property to the binding to define the selected shunt voltage gain.
This specifies the range and accuracy that applies to the shunt circuit.
This property only applies to devices that have a selectable shunt
voltage range via PGA or ADCRANGE register configuration.
