2dd33fc2a8 * Raw NAND changes:
i.MX8 and i.MX31 now have their own compatible, the Qcom driver got
 cleaned, the Broadcom driver got fixed.
 
 * SPI NAND changes:
 Two main features have been added:
 - OTP support has been brought, and ESMT and Micron manufacturer drivers
   implement it.
 - Read retry, and Macronix manufacturer driver implement it.
 
 There is as well a bunch of minor improvements and fixes in drivers and
 bindings.

59ee921ca7 SPI NOR adds support for few flashes. Few cleanup patches for the core
driver, where we touched the headers inclusion list and we start using
 the scope based mutex cleanup helpers.

GCC compiler is not happy about NULL being supplied as printf() parameter:

drivers/mtd/mtdpart.c:693:34: error: ‘%s’ directive argument is null [-Werror=format-overflow=]

Move the code after the parser test for NULL, and drop the ternary completely.
The user can deduct this since when it's not NULL two messages will be printed.

mtd: spi-nor: explicitly include <linux/of.h>
The core driver is using of_property_read_bool() and relies on implicit
inclusion of <linux/of.h>, which comes from <linux/mtd/mtd.h>.

It is good practice to directly include all headers used, it avoids
implicit dependencies and spurious breakage if someone rearranges
headers and causes the implicit include to vanish.

Include the missing header.

6697dae1e2 mtd: capture device name setting failure when adding mtd
syzbot reported a WARNING in release_mtd_partition. [1]

The reproducer uses "/proc/thread-self/fail-nth" to trigger the failure
of memory allocation when executing dev_set_name() in add_mtd_device(),
which eventually causes device_register() to fail because the device name
is not set, and finally triggers a warning in put_device().

The fix uses the higher level nand_reset(chip, chipnr); where chipnr = 0, when
doing PM resume operation in compliance with the controller support for single
die nand chip. Switching from nand_reset_op() to nand_reset() implies more
than just setting the cs field op->cs, it also reconfigures the data interface
(ie. the timings). Tested and confirmed the NAND chip is in sync timing wise
with host after the fix.

9b4db032fb mtd: spi-nor: winbond: Add support for w25q01jv
Add support for Winbond w25q01jv spi-nor chip.

This chip is internally made of two dies with linear addressing
capabilities to make it transparent to the user that two dies were
used. There is one drawback however, the read status operation is racy
as the status bit only gives the active die status and not the status of
the other die. For commands affecting the two dies, it means if another
command is sent too fast after the first die has returned a valid status
(deviation can be up to 200us), the chip will get corrupted/in an
unstable state.

This chip hence requires a better status register read. There are three
solutions here:

1- If we assume that the most common situation producing this problem is
status register writes, maybe we could change the "non-volatile"
status register write commands to become "volatile" status register
writes. In practice, what takes time is the write operation of the bits
themselves, and not the activation of the feature in the internal
circuitry. Enabling "volatile" status register writes would make the
writes nearly instant.

This approach, besides probably being the less impacting one, could
overlook other possible actions where both dies can be used at the same
time like a chip erase (or any erase over die boundaries in general).

2- Wait about 200us after getting a first status ready feedback. This
200us is about the maximum possible deviation between dies and would
cover all cases.

3- We iterate manually over all internal dies (which takes about 30us
per die) until all are ready. This approach will always be faster than
a blind delay which represents the maximum deviation, while also being
totally safe.

This third approach has been adopted. A flash-specific hook for the
status register read had to be implemented. Testing with the flash_speed
benchmark shown no difference with the existing performances (using the
regular status read core function). In practice there are difference in
the experimental results below, but they are part of the natural
deviation of the benchmark:

	> Without the fixup
	$ flash_speed /dev/mtd0 -c100 -d
	eraseblock write speed is 442 KiB/s
	eraseblock read speed is 1606 KiB/s
	page write speed is 439 KiB/s
	page read speed is 1520 KiB/s
	2 page write speed is 441 KiB/s
	2 page read speed is 1562 KiB/s
	erase speed is 68 KiB/s

	> With the fixup
	$ flash_speed /dev/mtd0 -c100 -d
	eraseblock write speed is 428 KiB/s
	eraseblock read speed is 1626 KiB/s
	page write speed is 426 KiB/s
	page read speed is 1538 KiB/s
	2 page write speed is 426 KiB/s
	2 page read speed is 1574 KiB/s
	erase speed is 66 KiB/s

However, the fixup, whatever which one we pick, must be applied on
multi-die chips, which hence must be properly flagged. The SFDP tables
implemented give a lot of information but the die details are part of an
optional table that is not implemented, hence we use a post parsing
fixup hook to set the params->n_dice value manually.
