That is not true. KS8737 would only attempt to set the led mode bits
if the device tree tries to set the led mode. Since KS8737 does not
have a led mode selection, the device tree should not have this, and
there is no problem.
If you want a device tree validator, then use the yaml dts spec to do
this in the proper way, at build time. The bootloader has the the
most constrained size of any part of a Linux system and is also the
most critical for device start up time. It is the worst possible
place to put a dts validator.

You again ignore there are two ways to do this. Make the kernel match
Barebox where the Barebox code is better.
