Subject: [PATCH AUTOSEL 5.18 07/39] riscv: dts: microchip: Add mpfs' topology information
Date: Sun, 14 Aug 2022 12:22:56 -0400	[thread overview]
Message-ID: <20220814162332.2396012-7-sashal@kernel.org> (raw)
In-Reply-To: <20220814162332.2396012-1-sashal@kernel.org>

From: Conor Dooley <conor.dooley@microchip.com>

[ Upstream commit 88d319c6abaeb37f0e2323275eaf57a8388e0265 ]

The mpfs has no cpu-map node, so tools like hwloc cannot correctly
parse the topology. Add the node using the existing node labels.
