sama5d4_xplained has an optional on-board serial DataFlash (AT25DF321A), which does not come populated on board by default. Since the spi0 node does not have any child populated by default, thus no user on sama5d4_xplained, remove it. This avoids the following error in SPI NOR, which reads the values of the pulled downed lines, unrecognizing the flash: spi-nor spi0.0: unrecognized JEDEC id bytes: 00 00 00 00 00 00 Signed-off-by: Tudor Ambarus <tudor.ambarus@microchip.com> --- arch/arm/boot/dts/at91-sama5d4_xplained.dts | 10 ---------- 1 file changed, 10 deletions(-)
