Subject: dm: core: Add an ofnode function to get the devicetree root
X-Git-Url: http://git.dujemihanovic.xyz/img/static/gitweb.css?a=commitdiff_plain;h=d0c20ce6bcb9af3d70ed6ada618607ca1099e811;p=u-boot.git

dm: core: Add an ofnode function to get the devicetree root

This is needed in at least one place. Avoid the conditional code in root.c
by adding this inline function.
