This patch does not apply cleanly. Your mail client may have wrapped
some of the longer lines.

Please add a longer commit message. It is customary to describe the
major features of the SoC in the initial commit.

Is this the correct capitalization for OpenPiton?

Please use a different compatible here, since you have already used the
one above for the whole device tree.

This node should be at the top level, not under /soc.

Please add a soc-specific compatible string. E.g. "openpiton,ns16550".
This makes it easier to address errata/quirks if they are discovered
later.

Can you check to see if this is still needed since d442f69399 ("common:
