[PATCH v4 12/16] spi: dw: Add DW SPI DMA/PCI/MMIO dependency on the DW SPI core

From: Serge Semin
Date: Thu May 21 2020 - 20:09:12 EST


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.
