• 5548f98c4   spi/pxa2xx: use GFP_ATOMIC in sg table allocation ... Browse Code »

  pxa2xx_spi_map_dma_buffer() gets called in tasklet context so we can't
  sleep when we allocate a new sg table. Use GFP_ATOMIC here instead.

• cddb339ba   spi/pxa2xx: convert to dma_request_slave_channel_compat() ... Browse Code »

  Now that we have these nice DMA API helper functions we can take advantage
  of those instead of open-coding the channel/request line extraction from
  ACPI. Use the _compat version which still allows passing the
  channel/request line from platform data.

• 5928808ef   spi/pxa2xx: add support for DMA engine ... Browse Code »

  To be able to use DMA with this driver on non-PXA platforms we implement
  support for the generic DMA engine API. This lets user to use different DMA
  engines with little or no modification to the driver.

  Request lines and channel numbers can be passed to the driver from the
  platform specific data.

  The DMA engine implementation will be selected by default even on PXA
  platform. User can select the legacy DMA API by enabling Kconfig option
  CONFIG_SPI_PXA2XX_PXADMA.
