-Subject: [PATCH] arm: dts: Improve the bcm27xx inclusion hierarchy
-
-1) The top-level .dts files now include parallel chains of bcm27xx.dtsi
- and bcm27xx-rpi.dtsi files, with no cross-inclusion between the two
- chains.
-
-2) Move definitions and deletions to the point of maximum commonality
- to reduce redundancy.
