Hi,

Just a quick drive-by review since I was looking at these patches in

These should be in alphanumerical order. 407 comes before 415. You've
been out of order with others as well.

This should go from specific to generic, so the order needs to be the other way.

Please check other dts files for the same (I didn't).

You might want to consider reference-based syntax here instead, so you
don't have to mimic the hierarchy. That'd be (at the root level of the
file, below this secion:

&sbc_serial0: {
        status = "okay";
};

Same for others.
