Pull mtd updates from Miquel Raynal:
"Core MTD changes:
- We must ignore error -ENOENT from parsers on subpartitions which is
a legitimate return value
- PM support is added to the intel-dg driver
Raw NAND changes:
- The major change in this is the support for the Allwinner H616 NAND
controller, which lead to numerous changes and cleanups in the
driver.
- Another notable change in this driver is the use of field_get() and
field_prep(), but since the global support for this helpers is
going to be merged in the same release as we start using these
helpers, we undefine them in the first place to avoid warnings.
- Marvell drivers layout handling changes have also landed, they fix
previous definitions and abuses that have been made previously,
which implied to relax the ECC parameters validation in the core a
bit.
- The Cadence NAND controller driver gets NV-DDR interface support.
SPI NAND changes:
- Support for FudanMicro FM25S01BI3 and ESMT F50L1G41LC is added.
SPI NOR changes:
- Fix SMPT parsing for S25FS-S flash family. They report variable
dummy cycles for reads. This results in the default of 0 being
used. This works for other Infineon chips, but not for the S25FS-S
family. They need 8 dummy cycles. Add fixup hooks to specify that.
Also add fixup hooks to fix incorrect map ID data in SFDP.
- Add support for a bunch of Winbond flashes. Their block protection
information is not discoverable, so they need to have an entry in
the flash tables to describe that.
- Some cleanups for Micron flash support.
- Add support for Micron mt35xu01gbba.
- Some SPI controllers like the Intel one on the PCI bus do not
support the read CR opcode (0x35). Do not use the opcode if the
controller does not support it.
Aside from these main changes, there is the usual load of API updates,
kdoc fixes, potential memory leaks fixes, etc"

strncpy() is deprecated [1] for NUL-terminated destination buffers
because it does not guarantee NUL termination. It also unnecessarily
NUL-pads the destination buffer if the source is shorter. Replace it
with sysfs_emit() using the "%.*s" format specifier and supply the
length 'sm_attr->len' to improve sm_attr_show().
Return the number of characters actually written to 'buf' instead of
'sm_attr->len'.

There are several places where a value of type 'int' is shifted by
lpddr->chipshift. lpddr->chipshift is derived from QINFO geometry and
might reach 31 when QINFO reports a 2 GiB size - the maximum supported by
LPDDR(1) compliant chips. This may cause unexpected sign-extensions when
casting the integer value to the type of 'unsigned long'.
Use '1UL << lpddr->chipshift' and cast 'j' to unsigned long before
shifting so the computation is performed at the destination width.

Some SPI controllers like Intel's one on the PCI bus do not support
opcode 35h. This opcode is used to read the Configuration Register on
SPI-NOR chips that have 16-bit Status Register configured regardless
of the controller support for it. Adding a check call in the setup step
allows disabling use of the 35h opcode and falling back to the manual
Status Registers management.

openat(AT_FDCWD, "/dev/mtd0", O_RDWR) = 4

The MT35XU02GCBA flash device does not support chip erase, according to
its datasheet. It supports die erase, which means the current driver
implementation will likely need to be converted to use die erase.
Furthermore, similar to the MT35XU01GBBA, the
SPI_NOR_IO_MODE_EN_VOLATILE flag probably needs to be enabled.
Currently no active contributor has access to this hardware so there is
no way of testing the fixes. Add a TODO item on the flash entry so
someone with the flash can test that the support is indeed broken and
send the fixes.

Besides, mt35xu01gbba do not support chip erase, but support

Commit 5c2f7727d437 ("mtd: mtdpart: check for subpartitions parsing
result") introduced some kind of regression with parser on subpartitions
where if a parser emits an error then the entire parsing process from the
upper parser fails and partitions are deleted.
Not checking for error in subpartitions was originally intended as
special parser can emit error also in the case of the partition not
correctly init (for example a wiped partition) or special case where the
partition should be skipped due to some ENV variables externally
provided (from bootloader for example)
One example case is the TRX partition where, in the context of a wiped
partition, returns a -ENOENT as the trx_magic is not found in the
expected TRX header (as the partition is wiped)
To better handle this and still keep some kind of error tracking (for
example to catch -ENOMEM errors or -EINVAL errors), permit parser on
subpartition to emit -ENOENT error, print a debug log and skip them
accordingly.
This results in giving better tracking of the status of the parser
(instead of returning just 0, dropping any kind of signal that there is
something wrong with the parser) and to some degree restore the original
logic of the subpartitions parse.
(worth to notice that some special partition might have all the special
header present for the parser and declare 0 partition in it, this is why
it would be wrong to simply return 0 in the case of a special partition
that is NOT init for the scanning parser)

S25FS-S family supports SMPT that helps to detect sector layout settings
in configuration registers, but some of parameters in the table are
wrong or undetermined so the fixups below are required.
Read Any Register op is used to read configuration registers that
related to sector map. The op requires 8 cycles latency by default.
Implement smpt_read_dummy() to set correct dummy cycles.
Map ID is structured by combination of CR3NV[3], CR1NV[2], and CR3NV[1].
However, in S25FS512S, CR3NV[1] is RFU and always 0, while map IDs
defined in the table assume it is always 1. Implement smpt_map_id() to
fix map ID for S25FS512S. Other densities in S25FS-S family (256Mb and
128Mb) don't need this fix as CR3NV[1] in those chips is configurable
and map IDs are correctly defined in SMPT.

Certain chips have inconsistent Sector Map Parameter Table (SMPT) data,
which leads to the wrong map ID being identified, causing failures to
detect the correct sector map.
To fix this, introduce smpt_map_id() into the struct spi_nor_fixups.
This function will be called after the initial SMPT-based detection,
allowing chip-specific logic to correct the map ID.
Infineon S25FS512S needs this fixup as it has inconsistency between map
ID definition and configuration register value actually obtained.

SMPT contains config detection info that describes opcode, address, and
dummy cycles to read sector map config. The dummy cycles parameter can
be SMPT_CMD_READ_DUMMY_IS_VARIABLE and in that case nor->read_dummy
(initialized as 0) is used. In Infineon flash chips, Read Any Register
command with variable dummy cycle is defined in SMPT. S25Hx/S28Hx flash
has 0 dummy cycle by default to read volatile regiters and
nor->read_dummy can work. S25FS-S flash has 8 dummy cycles so we need a
hook that can fix dummy cycles with actually used value.
Inroduce smpt_read_dummy() in struct spi_nor_fixups. It is called when
the dummy cycle field in SMPT config detection is 'varialble'.

function ends makes no sense. However the good thing is that the pointer

The H616 nand controller has the same base as A10/A23, with some
differences:
- mdma is based on chained buffers
- its ECC supports up to 80bit per 1024bytes
- some registers layouts are a bit different, mainly due do the stronger
ECC.
- it uses USER_DATA_LEN registers along USER_DATA registers.
- it needs a specific clock for ECC and MBUS.
Introduce the basic support, with ECC and scrambling, but without
DMA/MDMA.

The H6/H616 ECC_MODE field is not at the same offset, and has not the
same size.
So move the mask into sunxi_nfc_caps.
Also, introduce a non compile-time field_prep() because FIELD_PREP()
doesn't work with non compile-time constant.
No functional change.

The H616 controller can't handle 512 bytes ECC block size. The
NFC_ECC_BLOCK_512 bit disappeared in H6, and NDFC_RANDOM_EN took its
place.
So, add has_ecc_block_512 capability to only set this bit on SoC having
it.

On H6/H616, the register ECC_PAT_FOUND is at its own address, and not
part of ECC status register.
So, introduce the pattern found register offset in sunxi_nfc_caps, along
with its mask.
Also, introduce a non compile-time field_get() because FIELD_GET() and
u32_get_bits() don't work with non compile-time constant.
No functional change.

H6/H616 has more ECC strenghts than A10/A23.
Move the ECC strenghts array to sunxi_nfc_caps to make it ready for
H6/H616 support.

The user data length (4) used all over the code hard coded.
And sometimes, it's not that trivial to know that it's the user data
length and not something else.
Moreover, for the H6/H616 this value is no more fixed by hardware, but
could be modified.
Using a define here makes the code more readable.

The register NFC_REG_ECC_CTL was read twice and the result was not used,
then a third time with a mask applied.
Removing those calls didn't change the behavior.
Tested on H616 SoC, scrambling enabled.

The driver calls gpiod_get_optional() in the probe function but
never calls gpiod_put() in the remove function or in the probe
error path. This leads to a GPIO descriptor resource leak.
The lpc32xx_mlc.c driver in the same directory handles this
correctly by calling gpiod_put() on both paths.
Add gpiod_put() in the remove function and in the probe error path
to fix the resource leak.
