Merge tag 'mtd/for-6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux
Pull mtd updates from Miquel Raynal:
"MTD core changes:
- Fix refcount error in del_mtd_device()
- Fix possible resource leak in init_mtd()
- Set ROOT_DEV for partitions marked as rootfs in DT
- Describe marking rootfs partitions in the bindings
- Fix device name leak when register device fails in add_mtd_device()
- Try to find OF node for every MTD partition
- simplify (a bit) code find partition-matching dynamic OF node
MTD driver changes:
- pxa2xx-flash maps: fix memory leak in probe
- BCM parser: refer to ARCH_BCMBCA instead of ARCH_BCM4908
- lpddr2_nvm: Fix possible null-ptr-deref
- inftlcore: fix repeated words in comments
- lart: remove driver
- tplink:
- Add TP-Link SafeLoader partitions table parser and bindings
- Describe TP-Link SafeLoader parser
- Describe TP-Link SafeLoader dynamic subpartitions
- mtdoops:
- Panic caused mtdoops to call mtdoops_erase function immediately
- Add mtdoops_erase function and move mtdoops_inc_counter after it
- Change printk() to counterpart pr_ functions
MTD binding cleanup:
- Fixed-partitions: Fix 'sercomm,scpart-id' schema
- Standardize the style in the examples
- Drop object types when referencing other files
- Argue in favor of keeping additionalProperties set to true
- NVMEM-cells:
- Inherit from MTD partitions
- Drop range property from example
- Partitions:
- Change qcom,smem-part partition type
- Constrain the list of parsers
- Physmap: Reuse the generic definitions
- SPI-NOR: Drop common properties
- Sunxi-nand: Add an example to validate the bindings
- Onenand: Mention the expected node name
- Ingenic: Mark partitions in the controller node as deprecated
- NAND:
- Standardize the child node name
- Drop common properties already defined in generic files
- nand-chip.yaml should reference mtd.yaml
- Remove useless file about partitions
- Clarify all partition subnodes
SPI NOR core changes:
- Add support for flash reset using the dt reset-gpios property.
- Update hwcaps.mask to include 8D-8D-8D read and page program ops
when xSPI profile 1.0 table is defined.
- Bypass zero erase size in spi_nor_find_best_erase_type().
- Fix select_uniform_erase to skip 0 erase size
- Add generic flash driver. If a flash is not found in the flash_info
array, fall back to the generic flash driver which is described
solely by the flash's SFDP tables.
- Fix the number of bytes for the dummy cycles in
spi_nor_spimem_check_readop().
- Introduce SPI_NOR_QUAD_PP flag, as PP_1_1_4 is not SFDP
discoverable.
SPI NOR manufacturer drivers changes:
- Spansion:
- use PARSE_SFDP for s28hs512t,
- add support for s28hl512t, s28hl01gt, and s28hs01gt.
- Gigadevice: Replace default_init() with post_bfpt() for gd25q256.
- Micron - ST: Enable locking for mt25qu256a.
- Winbond: Add support for W25Q512NW-IQ.
- ISSI: Use PARSE_SFDP and SPI_NOR_QUAD_PP.
Raw NAND core changes:
- Drop obsolete dependencies on COMPILE_TEST
- MAINTAINERS: rectify entry for MESON NAND controller bindings
- Drop EXPORT_SYMBOL_GPL for nanddev_erase()
Raw NAND driver changes:
- marvell: Enable NFC/DEVBUS arbiter
- gpmi: Use pm_runtime_resume_and_get instead of pm_runtime_get_sync
- mpc5121: Replace NO_IRQ by 0
- lpc32xx_{slc,mlc}:
- Switch to using pm_ptr()
- Switch to using gpiod API
- lpc32xx_mlc: Switch to using pm_ptr()
- cadence: Support 64-bit slave dma interface
- rockchip: Describe rk3128-nfc in the bindings
- brcmnand: Update interrupts description in the bindings
SPI-NAND driver changes:
- winbond:
- Add Winbond W25N02KV flash support
- Fix flash identification"

Flash partitions in device tree
|
||||
===============================
|
||||
|
||||
Flash devices can be partitioned into one or more functional ranges (e.g. "boot
|
||||
code", "nvram", "kernel").
|
||||
|
||||
Different devices may be partitioned in a different ways. Some may use a fixed
|
||||
flash layout set at production time. Some may use on-flash table that describes
|
||||
the geometry and naming/purpose of each functional region. It is also possible
|
||||
to see these methods mixed.
|
||||
|
||||
To assist system software in locating partitions, we allow describing which
|
||||
method is used for a given flash device. To describe the method there should be
|
||||
a subnode of the flash device that is named 'partitions'. It must have a
|
||||
'compatible' property, which is used to identify the method to use.
|
||||
|
||||
When a single partition is represented with a DT node (it depends on a used
|
||||
format) it may also be described using above rules ('compatible' and optionally
|
||||
some extra properties / subnodes). It allows describing more complex,
|
||||
hierarchical (multi-level) layouts and should be used if there is some
|
||||
significant relation between partitions or some partition internally uses
|
||||
another partitioning method.
|
||||
|
||||
Available bindings are listed in the "partitions" subdirectory.
|
||||
|
||||
|
||||
Deprecated: partitions defined in flash node
|
||||
============================================
|
||||
|
||||
For backwards compatibility partitions as direct subnodes of the flash device are
|
||||
supported. This use is discouraged.
|
||||
NOTE: also for backwards compatibility, direct subnodes that have a compatible
|
||||
string are not considered partitions, as they may be used for other bindings.
