[PATCH 1/4] arm: dts: am335x-boneblack: Extract common config

Paul Barker paul.barker at sancloud.com
Thu Jun 17 11:02:19 CEST 2021


Configuration which is shared between the BeagleBone Black and
derivative boards like the Sancloud BeagleBone Enhanced (BBE) is moved
to a common dtsi file to prevent duplication.
