From: Niravkumar L Rabara <niravkumar.l.rabara at intel.com>

This patchset introduces improvements and fixes for cadence nand driver.
The changes include:

1. Support deferred prob mechanism when DMA driver is not probed yet.
2. Map the slave DMA address using dma_map_resource. When ARM SMMU
   is enabled, using a direct physical address of SDMA results in
   DMA transaction failure.
3. Fixed the incorrect device context used for dma_unmap_single.

Niravkumar L Rabara (3):
  mtd: rawnand: cadence: support deferred prob when DMA is not ready
  mtd: rawnand: cadence: use dma_map_resource for sdma address
  mtd: rawnand: cadence: fix incorrect dev context in dma_unmap_single
