Thanks for pointing out the dependencies!

My review is a bit rote since I don't actually know anything about
audio. This is mostly just a dt-hygiene review.

Missing unit address and also sorted incorrectly. Nodes should be
sorted by unit address.

Is there a pin config that generally makes sense for all boards? If
so, you can add it here so it doesn't need to be added to all
sub-boards.


> + reg = <0 0x62F00000 0 0x29000>;

nit: lower case hex for reg address, so 62f not 62F.

First entry of interrupts should be GIC_SPI, which is what 0 is referring to.

> + };

Bindings claim you're supposed to have:

#address-cells = <1>;
#size-cells = <0>;

Do you not need them for some reason?

Can you group together any of the configs? See, for instance,
"qup_spi0_default" where we configure 4 pins together. Then you don't
need so many separate nodes to add.

Also: pinconf is nearly always done in board files unless you truly
have a reason to believe that it would be the same for every board.
