Subject: [PATCH 264/323] arm64: dts: allwinner: h6: Add DAI node and soundcard
|
|
for HDMI
|
|
MIME-Version: 1.0
|
|
Content-Type: text/plain; charset=UTF-8

Content-Transfer-Encoding: 8bit
|
|
|
|
Add the I2S node used by the HDMI and a simple-soundcard to
|
|
link audio between HDMI and I2S.
|
|
|
|
Note that the HDMI codec requires an inverted frame clock and
|
|
a fixed I2S width. As there is no such option for I2S we use
|
|
TDM property of the simple-soundcard to do that.
