Subject: [PATCH AUTOSEL 5.4 05/16] riscv: dts: sifive: Add fu540 topology information
Date: Sun, 14 Aug 2022 12:28:20 -0400 [thread overview]
Message-ID: <20220814162833.2398478-5-sashal@kernel.org> (raw)
In-Reply-To: <20220814162833.2398478-1-sashal@kernel.org>
From: Conor Dooley <conor.dooley@microchip.com>
[ Upstream commit af8f260abc608c06e4466a282b53f1e2dc09f042 ]
The fu540 has no cpu-map node, so tools like hwloc cannot correctly
parse the topology. Add the node using the existing node labels.
