Subject: [PATCH v2 2/3] dt-bindings: clock: cs2000-cp: Document aux-output-source
Date: Wed, 19 May 2021 22:15:50 +0200	[thread overview]
Message-ID: <20210519201551.690654-3-daniel@zonque.org> (raw)
In-Reply-To: <20210519201551.690654-1-daniel@zonque.org>

This new optional property can be used to control the function of the
auxiliary output pin. Introduce a new dt-bindings include file that
contains the numerical values.
