The SPI NAND subsystem has seen the introduction of DTR operations (the
equivalent of DDR transfers), which involved quite a few preparation
patches for clarifying macro names.
In the raw NAND subsystem, the brcmnand driver has been "fixed" for old
legacy SoCs with an update of the ->exec_op() hook, there has been the
introduction of a new controller driver named Loongson-1, and the
Qualcomm driver has received quite a few misc fixes as well as a new
compatible.
Aside from this, there is the usual load of misc improvement and fixes.

SDX75 NAND controller has iommu support so define it in the properties
section.

* Raw NAND changes
A new controller driver, from Nuvoton, has been merged.
Bastien Curutchet has contributed a series improving the Davinci
controller driver, both on the organization of the code, but also on the
performance side. The binding has also been converted to yaml, received
a new OOB layout and now supports on-die ECC engines.
The Qualcomm controller driver has been deeply cleaned to extract some
parts of the code into a shared file with the Qualcomm SPI memory
controller.
Aside from these main changes, the Cadence binding has been converted to
yaml, the brcmnand controller driver has received a small fix, otherwise
some more minor changes have also made their way in.
* SPI NAND changes
The SPI NAND subsystem has seen a great improvement, with the advent of
DTR operations (DDR operations, which may be extended to the address
cycles). The first vendor driver to benefit from these improvements is
the Winbond driver.
A new manufacturer driver is added SkyHigh, with a new constraint for
the core, it is impossible to disable the on-die ECC engine.
A Foresee device is also now supported.

SPI NOR changes for 6.14
Notable changes:
- Add flash entries for Atmel AT25SF321, Spansion S28HL256T, S28HL02GT.
- Add support for vcc-supply regulators and their DT bindings.
- Drop mx25u25635f entry. The flash shares its ID with mx25u25645g and
both parts have an SFDP table. Removing their entry lets them be
driven by the generic SFDP-based driver.

SPI NOR changes:
- Drop support for Xilinx S3AN flashes. These flashes are for the
very old Xilinx Spartan 3 FPGAs and they need some awkward code in

Drop support for these flashes, along with the special handling we

and the .setup() callback.
- Fix regression for old w25q128 flashes without SFDP tables.
Commit 83e824a4a595 ("mtd: spi-nor: Correct flags for Winbond
w25q128") dropped support for such devices under the assumption
that they aren't being used anymore. Users have now surfaced [0] so
fix the regression by supporting both kind of devices.
- Core cleanups including removal of SPI_NOR_NO_FR flag and
simplification of spi_nor_get_flash_info()"

Convention is DT schemas should define all properties at the top-level
and not inside of if/then schemas. That minimizes the if/then schemas
and is more future proof.
There were 2 "if" schemas for "qcom,ipq806x-nand" and the
"qcom,boot-partitions: true" unnecessary, so the conditional schemas
can be simplified a bit.

Boot ROM code on Meson requires that some pages on NAND must be written
in special mode: "short" ECC mode where each block is 384 bytes and
scrambling mode is on. Such pages are located on the chip in the
following way (for example):
[ p0 ][ p1 ][ p2 ][ p3 ][ p4 ][ p5 ][ p6 ][ p7 ] ... [ pN ]
^ ^ ^ ^
pX is page number "X". "^" means "special" page used by boot ROM - e.g.
every 2nd page in the range of [0, 7]. Step (2 in example is set by
'amlogic,boot-page-step' field. Last page in range (7 in example) is
set by 'amlogic,boot-pages' field.

Add two compatibles for binman entries, as a starting point for the
schema.
Note that, after discussion on v2, we decided to keep the existing
meaning of label so as not to require changes to existing userspace
software when moving to use binman nodes to specify the firmware
layout.
Note also that, after discussion on v6, we decided to use the same
'fixed-partition' schema for the binman features, so this version
adds a new 'binman.yaml' file providing the new compatibles to the
existing partition.yaml binding.

Add three properties for controlling alignment of partitions, aka
'entries' in fixed-partition.
For now there is no explicit mention of hierarchy, so a 'section' is
just the 'fixed-partitions' node.
These new properties are inputs to the Binman packaging process, but are
also needed if the firmware is repacked, to ensure that alignment
constraints are not violated. Therefore they are provided as part of
the schema.

The main series brought is an update of the Broadcom support to support
all BCMBCA SoCs and their specificity (ECC, write protection,
configuration straps), plus a few misc fixes and changes in the main
driver. Device tree updates are also part of this PR, initially because
of a misunderstanding on my side.
The STM32_FMC2 controller driver is also upgraded to properly support
MP1 and MP25 SoCs.
A new compatible is added for an Atmel flavor.
Among all these feature changes, there is as well a load of continuous
read related fixes, avoiding more corner conditions and clarifying the
logic. Finally a few miscellaneous fixes are made to the core, the
lpx32xx_mlc, fsl_lbc, Meson and Atmel controller driver, as well as
final one in the Hynix vendor driver.
SPI-NAND
The ESMT support has been extended to match 5 bytes ID to avoid
collisions. Winbond support on its side receives support for W25N04KV
chips.

SPI NOR gets the non uniform erase code cleaned. We stopped using
bitmasks for erase types and flags, and instead introduced dedicated
members. We then passed the SPI NOR erase map to MTD. Users can now
determine the erase regions and make informed decisions on partitions
size.

Some spi flash memories have an interrupt signal which can be used for
signalling on-chip events such as busy status or ecc errors to the host.
Add binding for "interrupts" property so that boards wiring this signal
may describe the connection.

The mtd binding is always $ref'ed by other bindings, default selector
should be from other binding files which ref'ed it. Now, "$nodename" in
mtd.yaml turns into a "select" automatically such that a few binding check
issues reported because it conflicts with sram devices(eg, qcom,imem.yaml,
rules in folder sram/*)
To avoid the automatically created "select" in mtd.yaml, adding:
select: false

Pull mtd updates from Miquel Raynal:
"The main set of changes is related to Uwe's work converting platform
remove callbacks to return void. Comes next (in number of changes)
Kees' additional structures annotations to improve the sanitizers. The
usual amount of cleanups apply.
About the more substancial contribution, one main function of the
partitions core could return an error which was not checked, this is
now fixed. On the bindings side, fixed partitions can now have a
compression property. Finally, an erroneous situation is now always
avoided in the MAP RAM driver.
CFI:
- A several years old byte swap has been fixed.
NAND:
- The subsystem has, as usual, seen a bit of cleanup being done this
cycle, typically return values of platform_get_irq() and
devm_kasprintf(). There is also a better ECC check in the Arasan
driver. This comes with smaller misc changes.
- In the SPI-NAND world there is now support for Foresee F35SQA002G,
Winbond W25N and XTX XT26 chips.
SPI NOR:
- For SPI NOR we cleaned the flash info entries in order to have them
slimmer and self explanatory. In order to make the entries as slim
as possible, we introduced sane default values so that the actual
flash entries don't need to specify them. We now use a flexible
macro to specify the flash ID instead of the previous INFOx()
macros that had hardcoded ID lengths.
Instead of:
{ "w25q512nwm", INFO(0xef8020, 0, 64 * 1024, 0)
OTP_INFO(256, 3, 0x1000, 0x1000) },
We now use:
.id = SNOR_ID(0xef, 0x80, 0x20),
.name = "w25q512nwm",
.otp = SNOR_OTP(256, 3, 0x1000, 0x1000),
- We also removed some flash entries: the very old Catalyst SPI
EEPROMs that were introduced once with the SPI-NOR subsystem, and a
Fujitsu MRAM. Both should use the at25 EEPROM driver. The latter
even has device tree bindings for the at25 driver.
- We made sure that the conversion didn't introduce any unwanted
changes by comparing the .rodata segment before and after the
conversion. The patches landed in linux-next immediately after
v6.6-rc2, we haven't seen any regressions yet.
- Apart of the autumn cleaning we introduced a new flash entry,
at25ff321a, and added block protection support for mt25qu512a"

Support for old NVMEM fixed cells was deprecated in favour of
"fixed-layout". It's still part of the nvmem.yaml though and may be
unknowingly used by new bindings added without much of analyze.
To make it more difficult to accidentally support old syntax move its
binding to separated file with "deprecated" in its name.
