Subject: [PATCH 7/8] dt-bindings: adv748x: add information about serial audio interface (I2S/TDM)
Date: Mon, 13 Jan 2020 15:15:50 +0100 [thread overview]
Message-ID: <20200113141550.GH3606@pflmari> (raw)
In-Reply-To: <cover.1578924232.git.alexander.riesen@cetitec.com>
As the driver has some support for the audio interface of the device,
the bindings file should mention it.
