The `#sound-dai-cells` is not in the bindings. The bindings also say
`additionalProperties: false`. So either your patch is wrong for
including this or the bindings are wrong for omitting it. Which is it?
I notice that downstream we don't have this.

Ideally you'll want to rebase to make context clean since the above
got changed from `max98357a` to `max98360a`.

I am certainly not an expert, but I notice that downstream we have reg
as <LPASS_DP_RX>, which makes the node name dai-link@5 instead of @2.
Does that matter?

Your node name and `reg` don't match. `LPASS_DP_RX` is 5 so the node
name should include @5, not @0. I also notice that downstream the node
name is called `hdmi`, not `hdmi-primary`. The downstream `hdmi` seems
more parallel to the sibling nodes, like `mi2s@0` and `mi2s@1`.
