Subject: [PATCH 4/9] arm64: dts: marvell: Drop SPI max frequency
Date: Wed, 11 Nov 2026 16:43:01 -0600 [thread overview]
Message-ID: <20261111-dtbs-marvell-v1-4-938788aff3ae@kernel.org> (raw)
In-Reply-To: <20261111-dtbs-marvell-v1-0-938788aff3ae@kernel.org>
Remove spi-max-frequency from the CP0 SPI controller node on the
CN9130 SolidRun SOM. The property belongs on SPI devices, and the
flash child already has its own maximum frequency. Plus, pretty
sure 1.8GHz is not a possible SPI bus frequency.
