Nope, wrong flag. This is a hint for us that you based your DTS on
something ancient (e.g. broken downstream stuff). Please start from
*scratch* and write your DTS based on a board taken from mainline.

There is no point for us to repeat review for all the things  we already
fixed in mainline.

Node names should be generic.

We can't fully do that, as we don't have access to the schematics for
the board. What we can do, however, is to compare this .dts to others
from mainline and investigate all differences to see if they can be
bugs.

The upstreaming process is rather to take a DTS from the mainline and
customize it. Add stuff, remove something, change other nodes. Several
pieces are similar between boards, like the PMIC. I think this patch was
done in other way - entire PMIC was taken from downstream - therefore I
recommend the previous approach. It does not mean that everything should
be done from 0 but rather based on mainline DTS to avoid the same
mistakes we already fixed. Many times...

Krzysztof
