Subject: [PATCH v3 0/9] Some fixes for spi-s3c64xx

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.

Łukasz Stelmach (9):
  spi: spi-s3c64xx: swap s3c64xx_spi_set_cs() and
    s3c64xx_enable_datapath()
  spi: spi-s3s64xx: Add S3C64XX_SPI_QUIRK_CS_AUTO for Exynos3250
  spi: spi-s3c64xx: Check return values
  spi: spi-s3c64xx: Report more information when errors occur
  spi: spi-s3c64xx: Rename S3C64XX_SPI_SLAVE_* to S3C64XX_SPI_CS_*
  spi: spi-s3c64xx: Fix doc comment for struct s3c64xx_spi_driver_data
  spi: spi-s3c64xx: Ensure cur_speed holds actual clock value
  spi: spi-s3c64xx: Increase transfer timeout
  spi: spi-s3c64xx: Turn on interrupts upon resume
