      fsldma: Add a completed cookie updated action in DMA finish interrupt. · 9c98718e
      Zhang Wei 提交于
      The patch 'fsldma: do not cleanup descriptors in hardirq context'
      (commit 222ccf9a) removed descriptors
      cleanup function to tasklet but the completed cookie do not updated.
      Thus, the DMA controller will get lots of duplicated transfer
      interrupts. Just make a completed cookie update in interrupt handler.
      And keep other cleanup jobs in tasklet function.

      fsldma: Add device_prep_dma_interrupt support to fsldma.c · 2187c269
      Zhang Wei 提交于
      This is a bug that I assigned DMA_INTERRUPT capability to fsldma
      but missing device_prep_dma_interrupt function. For a bug in
      dmaengine.c the driver passed BUG_ON() checking. The patch fixes it.
