Raw Blame History

From 0da79aa7182e4102b4ee003ecb33ab85a30e08e7 Mon Sep 17 00:00:00 2001
From: Phil Elwell <phil@raspberrypi.org>
Date: Tue, 4 Jun 2019 16:22:22 +0100
Subject: [PATCH 663/782] 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.
