I'm hitting a conflict here, can you please rebase this series on top
of aspeed/dt from [1]?

Can you please fix the indentation here?

And again here?

Please check the entire devicetree for similar issues.

Please make sure the devicetree meets the style guide[2], particularly
the order of nodes:

https://docs.kernel.org/devicetree/bindings/dts-coding-style.html#order-of-nodes

Here, devices should be listed in ascending order of address.

Please check the entire devicetree.
