Hi All,

we are trying to add a new peripheral to SPI BUS Interface in LS1021A-TWR based board, we have some doubts about that

      which is the SPI master driver that needs to be enabled in kernel.

and in our present Linux SDK QorIQ-SDK-V1.8, DSPI interface support is there in Linux Device Tree and DSPI master driver spi-fsl-dspi is enabled in kernel configuration. we are not using any dspi, how to add SPI interface and new device to the Device Tree.
