Subject: [PATCH v2 2/3] dt-bindings: hwmon: ti,ina2xx: Add ti,shunt-gain property
Date: Wed, 27 Oct 2021 07:42:12 +0000 [thread overview]
Message-ID: <20211027074212.690611-2-nathan@nathanrossi.com> (raw)
In-Reply-To: <20211027074212.690611-0-nathan@nathanrossi.com>
From: Nathan Rossi <nathan.rossi@digi.com>
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.
Signed-off-by: Nathan Rossi <nathan.rossi@digi.com>

Changes in v2:
- Added binding for shunt-gain
