Subject: soc: imx8: Use existing of_root directly
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=283172b01956e9281885dccee9fb9727e07a55e0;p=linux.git

soc: imx8: Use existing of_root directly

There is common of_root for reference, no need to find it
from DT again, use of_root directly to make driver simple.
