Subject: [PATCH] powerpc: dts: Remove "spidev" nodes
Date: Fri, 17 Dec 2021 16:14:00 -0600	[thread overview]
Message-ID: <20211217221400.3667133-1-robh@kernel.org> (raw)

"spidev" is not a real device, but a Linux implementation detail. It has
never been documented either. The kernel has WARNed on the use of it for
over 6 years. Time to remove its usage from the tree.
