[PATCH] sync helios4 config to clearfog and dts to kernel

dgilmore at redhat.com dgilmore at redhat.com
Sat Jun 27 22:00:16 CEST 2020 

From: Dennis Gilmore <dennis at ausil.us>

The helios4 is built on the same microsom as the clearfog, by syncing the config
we enable the same featureset that exists in the som on the helios4. The current
config does not boot as some of the clearfog changes needed to be made on the
helios4 also, generally speaking most changes for the clearfog should also be
made on the helios4.
