    Subject[PATCH v6 12/16] spi: dw: Add DW SPI DMA/PCI/MMIO dependency on the DW SPI core
    Date
    Seeing all of the DW SPI driver components like DW SPI DMA/PCI/MMIO
    depend on the DW SPI core code it's better to use the if-endif
    conditional kernel config statement to signify that common dependency.
