[PATCH v6 12/16] spi: dw: Add DW SPI DMA/PCI/MMIO dependency on the DW SPI core

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
