[v3,0/9] Some fixes for spi-s3c64xx

Message

This is a series of fixes created during porting a device driver (these
patches will be released soon too) for an SPI device to the current kernel.

The two most important are

  spi: spi-s3c64xx: swap s3c64xx_spi_set_cs() and s3c64xx_enable_datapath()
  spi: spi-s3s64xx: Add S3C64XX_SPI_QUIRK_CS_AUTO for Exynos3250

Without them DMA transfers larger than 512 bytes from the SPI controller
would fail.
