      spi: spi-fsl-dspi: Free DMA memory with matching function · 03fe7aaf
      Krzysztof Kozlowski authored
      Driver allocates DMA memory with dma_alloc_coherent() but frees it with
      dma_unmap_single().
      
      This causes DMA warning during system shutdown (with DMA debugging) on
      Toradex Colibri VF50 module:

      spi: tools: Add macro definitions to fix build errors · 7bb64402
      Qing Zhang authored
      Add SPI_TX_OCTAL and SPI_RX_OCTAL to fix the following build errors:
      
      CC       spidev_test.o
      spidev_test.c: In function ‘transfer’:
      spidev_test.c:131:13: error: ‘SPI_TX_OCTAL’ undeclared (first use in this function)
        if (mode & SPI_TX_OCTAL)
                   ^
      spidev_test.c:131:13: note: each undeclared identifier is reported only once for each function it appears in
      spidev_test.c:137:13: error: ‘SPI_RX_OCTAL’ undeclared (first use in this function)
        if (mode & SPI_RX_OCTAL)

        LD       spidev_test-in.o
      ld: cannot find spidev_test.o: No such file or directory
      
      Additionally, maybe SPI_CS_WORD and SPI_3WIRE_HIZ will be used in the future,
      so add them too.
