Subject: [PATCH] ARM: dts: at91: sama5d4_xplained: Mark optional AT25DF321A as disabled
Date: Tue, 22 Jun 2021 16:42:22 +0300 [thread overview]
Message-ID: <20210622134222.107806-1-tudor.ambarus@microchip.com> (raw)
sama5d4_xplained has an optional on-board serial DataFlash (AT25DF321A),
which does not come populated on board by default. Mark it as disabled
to avoid the following probe error:
spi-nor spi0.0: unrecognized JEDEC id bytes: 00 00 00 00 00 00
