Subject[PATCH v5 12/20] arm64: dts: allwinner: a64: Add DAI node and soundcard for HDMI
Date
From: Marcus Cooper <codekipper@gmail.com>

Add the new DAI block for I2S2 which is used for HDMI audio
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.
