You are again confusing node names with node labels.
And it doesn't match what your commit message says.

The node name is what never changes even when the device
tree is compiled into a binary blob. The label gets compiled
out, and any references to it are converted to an integer
index, much like how a goto label in C gets compiled.

Of the two, the node name is what I asked to be changed.
Please take a look at arch/arm/boot/dts/sun8i-a83t.dtsi
for a proper example of what I am asking for. Note that
node names should use hyphens, not underscores, while
labels should use underscores. For the pinmux nodes
the name and label would likely be the same except for
this exception. So your uart0 label changes are good.
Please keep them.

I'm not sure why you changed this label. It doesn't make sense.
