Subject: [PATCH v2 07/10] dt-bindings: adv748x: add information about serial audio interface (I2S/TDM)
Date: Thu, 19 Mar 2020 18:42:36 +0100	[thread overview]
Message-ID: <c9ff553f804f178a247dca356306948e971432fb.1584639664.git.alexander.riesen@cetitec.com> (raw)
In-Reply-To: <cover.1584639664.git.alexander.riesen@cetitec.com>

As the driver has some support for the audio interface of the device,
the bindings file should mention it.
