[PATCHv2 0/6] dmaengine: introduce is_slave_xfer helper

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

There is a common practice to distinguish slave type transfers by checking
direction of the channel. This series introduces the check helper and its usage
across the drivers.

Since v1:
 - append commit messages to the all patches
 - update description for the patches against dw_dmac and at_hdmac
 - apply all current Reviewed-by and Acked-by tags

Andy Shevchenko (6):
  dmaengine: introduce is_slave_xfer function
  dma: at_hdmac: check direction properly for cyclic transfers
  dma: dw_dmac: check direction properly in dw_dma_cyclic_prep
  dma: ep93xx_dma: reuse is_slave_xfer helper
  dma: ipu_idmac: reuse is_slave_xfer helper
  dma: ste_dma40: reuse is_slave_xfer helper
