Last sentence is redundant. I asked to explain the hardware, not to tell
us how Devicetree works. Write concise and informative commit msgs which
tell non-obvious things. Not what you did. I alreaded asked this - do
not state the obvious, do not copy the subject.

The only useful part of your commit msg is first sentence - two lines,
so 33%. Remaining four lines, so 66%, is obvious.

Best regards,
Krzysztof
