Subject: [PATCH 3/6] ARM: dts: Move BCM2711 RPi specific into separate dtsi
Date: Sun, 30 May 2021 11:26:12 +0200	[thread overview]
Message-ID: <1622366775-5309-4-git-send-email-stefan.wahren@i2se.com> (raw)
In-Reply-To: <1622366775-5309-1-git-send-email-stefan.wahren@i2se.com>

There is a lot of Raspberry Pi specific stuff (neither SoC or board
specific) for the BCM2711 which is currently in the RPi 4 B dts. In order
to avoid copy & paste for every new BCM2711 based Raspberry Pi, move it
into a separate dtsi.
