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.
