I assumed that Neil has picked the series of the changes and tested the 
charge control limit functionality on his T14S device.

When I run "b4 trailers -u", the tag was added on all patches. I will 
remove the "Tested-by" trailer for the patches with functionality not 
applicable for X1E80100 platform.
