[PATCH v3 0/9] mtd: nand: add sunxi NAND Flash Controller support

[Boris BREZILLON]

This series adds support for the sunxi NAND Flash Controller (NFC).

I'll split this series for the next round:
1) NAND timings
2) sunxi NAND controller driver

But I'd like to have some feedback on the NAND timings stuff before doing this.

Any review on the sunxi driver is welcome (for the moment I only got feedback
on the NAND timings code).

I also have patches adding support for HW randomizer and per ECC partition
config that you can find here:

But I'd like to get the sunxi NAND driver mainlined before adding more
intrusive parts.

Best Regards,

Boris

Changes since v2:
 - merge HW ECC implementation in base implementation patch
 - fix timing config when interfacing with an ONFI compatible chip

Changes since v1:
 - add HW ECC support
 - rework NAND timings retrieval (use ONFI timing mode instead of raw timings)
 - add nand-ecc-level property to specify NAND ECC requirements from DT
