Subject: [PATCH v5 3/7] dt-bindings: iio: adc: ad7380: add pseudo-differential parts
Date: Tue, 19 Mar 2024 11:11:24 +0100 [thread overview]
Message-ID: <20240319-adding-new-ad738x-driver-v5-3-ce7df004ceb3@baylibre.com> (raw)
In-Reply-To: <20240319-adding-new-ad738x-driver-v5-0-ce7df004ceb3@baylibre.com>
From: David Lechner <dlechner@baylibre.com>
Adding AD7383 and AD7384 compatible parts that are pseudo-differential.
Pseudo-differential require common mode voltage supplies, so add them
conditionally
