[PATCH v1 0/8] spi: Rework DMA mapped flag

[Andy Shevchenko]

The first part of the series (patches 1 to 7) is an introduction
of a new helper followed by the user conversion.

This consolidates the same code and also makes patch 8 (last one)
be localised to the SPI core part.

The last patch is the main rework to get rid of a recently introduced
hack with a dummy SG list and move to the transfer-based DMA mapped
flag. 

That said, the patches 1 to 7 may be applied right away since they
have no functional change intended, while the last one needs more
testing and reviewing.

Andy Shevchenko (8):
  spi: Introduce internal spi_xfer_is_dma_mapped() helper
  spi: dw: Use new spi_xfer_is_dma_mapped() helper
  spi: ingenic: Use new spi_xfer_is_dma_mapped() helper
  spi: omap2-mcspi: Use new spi_xfer_is_dma_mapped() helper
  spi: pxa2xx: Use new spi_xfer_is_dma_mapped() helper
  spi: pci1xxxx: Use new spi_xfer_is_dma_mapped() helper
  spi: qup: Use new spi_xfer_is_dma_mapped() helper
  spi: Rework per message DMA mapped flag to be per transfer
