I lost stdout-path feedback, so I'll revise to following format in next version contribute:
chosen {
stdout-path = "serial4:57600n8";
};

As former feedback mentioned, I also revise the i2c device node names by referencing DT specification.
The only node name I used that not on the list is "power-sensor",
which is following the example under Documentation/devicetree/bindings.

Most of the other partition in DTS is same as the recent-contributed project.
Would you please to tell if there's still some omissions I made.
Thank you for reviewing.
