I see that this is the only sound related node not dependent on any
.dtsi nodes, but how useful is it to have it in here on its own?
Shouldn't we wait until all sound nodes are agreed upon and merged?

Nit: please add an empty line here, to separate the slave section from
the master.

Do you have any plans on upstreaming this binding?

I think you can drop this.

Why these two? I see that they save 219 bytes of the SPL, but the image
size is still way below the limit.
So I'd prefer to not deviate from the other boards here.

Why this one? Doesn't seem to affect SPL size?
