Thank you for your patch. There are no DTS users of this binding, so
while such conversions are useful, they have significantly smaller
impact. In the future, please consider converting bindings from active
platforms (arm64 defconfig, arm multi_v7). This would have significantly
bigger impact.

In the future for other patches like this, make example complete, so add
a dai-cells also here.

No need to resend just for that.
