Subject: [PATCH v4 8/9] dt-bindings: adv748x: add information about serial audio interface (I2S/TDM)
Date: Thu, 26 Mar 2020 11:35:43 +0100 [thread overview]
Message-ID: <37482bdfc6d6c6e231c58550b6bc4582aa29dde0.1585218857.git.alexander.riesen@cetitec.com> (raw)
In-Reply-To: <cover.1585218857.git.alexander.riesen@cetitec.com>
As the driver has some support for the audio interface of the device,
the bindings file should mention it.

v3: remove optionality off MCLK clock cell to ensure the description
matches the hardware no matter if the line is connected.
