Subject: [PATCH v2 2/3] dt-bindings: iio: adc: mcp3911: add reset-gpios
Date: Mon, 28 Apr 2025 08:54:12 +0200 [thread overview]
Message-ID: <20250428-mcp3911-fixes-v2-2-406e39330c3d@gmail.com> (raw)
In-Reply-To: <20250428-mcp3911-fixes-v2-0-406e39330c3d@gmail.com>
The MCP391X family provides an active low reset signal that is still not
described in the bindings.
Add reset-gpios to the bindings and the example.
