Subject: [PATCH v3 0/3] mtd: rawnand: cadence: improvement and fixes

From: Niravkumar L Rabara <niravkumar.l.rabara@...el.com>

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

1. Replace dma_request_channel() with dma_request_chan_by_mask() and use
   helper functions to return proper error code instead of fixed -EBUSY.
2. Remap the slave DMA I/O resources to enhance driver portability.
3. Fixed dma_unmap_single to use correct physical/bus device.


v3 changes:-
  * Update commit message based on v2 review feedback for better clarity.
  * Use dma_request_chan_by_mask() and helper functions to return proper
    error code instead of fixed -EBUSY error code.
