Thanks!

This will be very helpful when sending the next version.

If you like, you can also apply the following 9 patches cleanly in this order.

18/53 mtd: nand: denali: use nand_chip to hold frequently accessed data
19/53 mtd: nand: denali: call nand_set_flash_node() to set DT node
20/53 mtd: nand: denali: do not set mtd->name
21/53 mtd: nand: denali: move multi device fixup code to a helper function
22/53 mtd: nand: denali: simplify multi device fixup code
23/53 mtd: nand: denali: set DEVICES_CONNECTED 1 if not set
24/53 mtd: nand: denali: remove meaningless writes to read-only registers
25/53 mtd: nand: denali: remove unnecessary writes to ECC_CORRECTION
36/53 mtd: nand: denali: remove meaningless pipeline read-ahead operation

These are less controversial, and have no dependency on 10/53-17/53.




50/53 "mtd: nand: allocate aligned buffers if NAND_OWN_BUFFERS is unset"
is a change to the NAND framework. (used as a pre-requisite for 51/53)

Surely no dependency on the others, but If you wait more for comments
from other developers, that's no problem.



I will update the commented parts,
and hopefully send v3 next week.

Thanks!
