Merge tag 'mtd/for-5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux
Pull mtd updates from Miquel Raynal:
"MTD core changes:
- Spelling
- http to https updates
NAND core changes:
- Drop useless 'depends on' in Kconfig
- Add an extra level in the Kconfig hierarchy
- Trivial spellings
- Dynamic allocation of the interface configurations
- Dropping the default ONFI timing mode
- Various cleanup (types, structures, naming, comments)
- Hide the chip->data_interface indirection
- Add the generic rb-gpios property
- Add the ->choose_interface_config() hook
- Introduce nand_choose_best_sdr_timings()
- Use default values for tPROG_max and tBERS_max
- Avoid redefining tR_max and tCCS_min
- Add a helper to find the closest ONFI mode
- bcm63xx MTD parsers: simplify CFE detection
Raw NAND controller drivers changes:
- fsl-upm: Deprecation of specific DT properties
- fsl_upm: Driver rework and cleanup in favor of ->exec_op()
- Ingenic: Cleanup ARRAY_SIZE() vs sizeof() use
- brcmnand: ECC error handling on EDU transfers
- brcmnand: Don't default to EDU transfers
- qcom: Set BAM mode only if not set already
- qcom: Avoid write to unavailable register
- gpio: Driver rework in favor of ->exec_op()
- tango: ->exec_op() conversion
- mtk: ->exec_op() conversion
Raw NAND chip drivers changes:
- toshiba: Implement ->choose_interface_config() for TH58NVG2S3HBAI4,
TC58NVG0S3E, and TC58TEG5DCLTA00
- hynix: Implement ->choose_interface_config() for H27UCG8T2ATR-BC
SPI NOR core changes:
- Disable Quad Mode in spi_nor_restore().
- Don't abort BFPT parsing when QER reserved value is used.
- Add support/update capabilities for few flashes.
- Drop s70fl01gs flash: it does not support RDSR(05h) which is
critical for erase/write.
- Merge the SPIMEM DTR bits in spi-nor/next to avoid conflicts during
the release cycle.
SPI NOR controller drivers changes:
- Move the cadence-quadspi driver to spi-mem. The series was taken
through the SPI tree. Merge it also in spi-nor/next to avoid
conflicts during the release cycle.
- intel-spi:
- Add new PCI IDs.
- Ignore the Write Disable command, the controller doesn't support
it.
- Fix performance regression"
