Subject: [PATCH 3/5] arm64: dts: arm/corstone1000: Move cpu nodes
Date: Fri, 20 Mar 2026 11:47:16 -0500 [thread overview]
Message-ID: <20260320-dt-corstone1000-a320-v1-3-a549dfcfe8da@kernel.org> (raw)
In-Reply-To: <20260320-dt-corstone1000-a320-v1-0-a549dfcfe8da@kernel.org>
In preparation to add a new Corstone-1000 variation with different CPUs,
move the CPU nodes into the specific platforms and out of the common
corstone1000.dtsi.
