* v4:

1. Added Acked-by from Rob for DT documentation patches
2. Removed ipq8074 compatible string from ipq4019 DT example.
2. Used the BIT macro for NAND_CMD_VLD bits and consistent names
as suggested by Boris in v3.

* v3:

1. Removed the patches already applied to linux-next and
rebased the remaining patches on [1]
2. Reordered the patches and put the BAM DMA changes [2]
dependent patches and compatible string patches in last
3. Removed the register offsets array and used the dev_cmd offsets
4. Changed some macro names to small letters for better code readability
5. Changed the compatible string to SoC specific
6. Did minor code changes for adding comment, error handling, structure names
7. Combined raw write (patch#18) and passing flag parameter (patch#22) patch
into one
8. Made separate patch for compatible string and NAND properties
9. Made separate patch for BAM command descriptor and data descriptors handling
10. Changed commit message for some of the patches
11. Addressed review comments given in v2
12. Added Reviewed-by of Archit for some of the patches from v2
13. All the MTD tests are working fine for IPQ8064 AP148, IPQ4019 DK04 and
IPQ8074 HK01 boards for v3 patches

* v2:

1. Addressed the review comments given in v1
2. Removed the DMA coherent buffer for register read and used
streaming DMA API’s
3. Reorganized the NAND read and write functions
4. Separated patch for driver and documentation changes
5. Changed the compatible string for EBI2

* v1:
