Subject: [PATCH v7 2/2] ARM: dts: imx6: update spdif sound card node properties
The merge of imx-spdif driver into fsl-asoc-card brought
new DT properties that can be used with the "fsl,imx-audio-spdif"
compatible:
* The "spdif-controller" property from imx-spdif is named "audio-cpu"
in fsl-asoc-card.
* fsl-asoc-card uses codecs explicitly declared in DT
with "audio-codec".
With an S/PDIF, codec drivers spdif_transmitter and
spdif_receiver should be used.
Driver imx-spdif used instead the dummy codec and a pair of
boolean properties, "spdif-in" and "spdif-out".
While backward compatibility is kept to support properties
"spdif-controller", "spdif-in" and "spdif-out", using new properties has
several benefits:
* "audio-cpu" and "audio-codec" are more generic names reflecting
that the fsl-asoc-card driver supports multiple hardware.
They are properties already used by devices using the
fsl-asoc-card driver.
They are also similar to properties of simple-card: "cpu" and "codec".
* "spdif-in" and "spdif-out" imply the use of the dummy codec in the
driver. However, there are already two codec drivers for the S/PDIF,
spdif_transmitter and spdif_receiver.
It is better to declare S/PDIF Tx and Rx devices in a DT, and then
reference them with "audio-codec" than using the dummy codec.
For those reasons, this commit updates in-tree DTs to use the new
properties:
* Rename "spdif-controller" property to "audio-cpu".
* Declare S/PDIF transmitter and/or receiver devices, and use them with
the "audio-codec" property instead of "spdif-out" and/or "spdif-in".
These modifications were tested only on an imx8mn-evk board.
Note that out-of-tree and old DTs are still supported.
