Subject: [PATCH] ARM: dts: renesas: condor: Enable SPI NOR fast-read
Date: Thu, 22 Dec 2022 22:17:20 +0100	[thread overview]
Message-ID: <20221222211720.143390-1-marek.vasut@gmail.com> (raw)

From: Marek Vasut <marek.vasut+renesas@gmail.com>

This board requires SPI NOR fast-read, otherwise the SPI NOR
access returns corrupted data. Enable the fast-read explicitly
in DT as it has been disabled in the MTD subsystem by commit
d008190920 ("mtd: spi-nor: Mask out fast read if not requested in DT")
