From: Frieder Schrempf <frieder.schrempf@xxxxxxxxxx> The FSL QSPI driver will be moved to the SPI framework and it then acts as a SPI controller. Therefore the subnodes need to set spi-[rx/tx]-bus-width = <4>, so quad mode is used just as before. Also the properties 'num-cs' and 'bus-num' were never read by the driver and can be removed. The property 'fsl,qspi-has-second-chip' is not needed anymore and will be removed after the old driver was disabled to avoid breaking fsl-ls1046a-rdb.dts.
