Pull MTD updates from Miquel Raynal:
"MTD core changes:
- Fix issue where write_cached_data() fails but write() still returns
success
- maps: sa1100-flash: Replace zero-length array with flexible-array
member
- phram: Fix a double free issue in error path
- Convert fallthrough comments into statements
- MAINTAINERS: Add the IRC channel to the MTD related subsystems
Raw NAND core changes:
- Add support for manufacturer specific suspend/resume operation
- Add support for manufacturer specific lock/unlock operation
- Replace zero-length array with flexible-array member
- Fix a typo ("manufecturer")
- Ensure nand_soft_waitrdy wait period is enough
Raw NAND controller driver changes:
- Brcmnand:
* Add support for flash-edu for dma transfers (+ bindings)
- Cadence:
* Reinit completion before executing a new command
* Change bad block marker size
* Fix the calculation of the avaialble OOB size
* Get meta data size from registers
- Qualcom:
* Use dma_request_chan() instead dma_request_slave_channel()
* Release resources on failure within qcom_nandc_alloc()
- Allwinner:
* Use dma_request_chan() instead dma_request_slave_channel()
- Marvell:
* Use dma_request_chan() instead dma_request_slave_channel()
* Release DMA channel on error
- Freescale:
* Use dma_request_chan() instead dma_request_slave_channel()
- Macronix:
* Add support for Macronix NAND randomizer (+ bindings)
- Ams-delta:
* Rename structures and functions to gpio_nand*
* Make the driver custom I/O ready
* Drop useless local variable
* Support custom driver initialisation
* Add module device tables
* Handle more GPIO pins as optional
* Make read pulses optional
* Don't hardcode read/write pulse widths
* Push inversion handling to gpiolib
* Enable OF partition info support
* Drop board specific partition info
* Use struct gpio_nand_platdata
* Write protect device during probe
- Ingenic:
* Use devm_platform_ioremap_resource()
* Add dependency on MIPS || COMPILE_TEST
- Denali:
* Deassert write protect pin
- ST:
* Use dma_request_chan() instead dma_request_slave_channel()
Raw NAND chip driver changes:
- Toshiba:
* Support reading the number of bitflips for BENAND (Built-in ECC NAND)
- Macronix:
* Add support for deep power down mode
* Add support for block protection
SPI-NAND core changes:
- Do not erase the block before writing a bad block marker
- Explicitly use MTD_OPS_RAW to write the bad block marker to OOB
- Stop using spinand->oobbuf for buffering bad block markers
- Rework detect procedure for different READ_ID operation
SPI-NAND driver changes:
- Toshiba:
* Support for new Kioxia Serial NAND
* Rename function name to change suffix and prefix (8Gbit)
* Add comment about Kioxia ID
- Micron:
* Add new Micron SPI NAND devices with multiple dies
* Add M70A series Micron SPI NAND devices
* identify SPI NAND device with Continuous Read mode
* Add new Micron SPI NAND devices
* Describe the SPI NAND device MT29F2G01ABAGD
* Generalize the OOB layout structure and function names
SPI NOR core changes:
- Move all the manufacturer specific quirks/code out of the core, to
make the core logic more readable and thus ease maintenance.
- Move the SFDP logic out of the core, it provides a better
separation between the SFDP parsing and core logic.
- Trim what is exposed in spi-nor.h. The SPI NOR controllers drivers
must not be able to use structures that are meant just for the SPI
NOR core.
- Use the spi-mem direct mapping API to let advanced controllers
optimize the read/write operations when they support direct
mapping.
- Add generic formula for the Status Register block protection
handling. It fixes some long standing locking limitations and eases
the addition of the 4bit block protection support.
- Add block protection support for flashes with 4 block protection
bits in the Status Register.
SPI NOR controller drivers changes:
- The mtk-quadspi driver is replaced by the new spi-mem spi-mtk-nor
driver.
- Merge tag 'mtk-mtd-spi-move' into spi-nor/next to avoid conflicts.
HyperBus changes:
- Print error msg when compatible is wrong or missing
- Move mapping of direct access window from core to individual
drivers"
