I mean, really think about it, why do you allow 1024 only for your variant and then immediately allow for all variants? This does not make sense. If you tested with proper patch you would see: elba-asic.dtb: spi@2400: cdns,fifo-depth:0:0: 1024 is not one of [128, 256] > default: 128 > > cdns,fifo-width: Best regards, Krzysztof
