Merge tag 'mtd/for-4.21' of git://git.infradead.org/linux-mtd
Pull mtd updates from Boris Brezillon:
"SPI NOR Core changes:
- Parse the 4BAIT SFDP section
- Add a bunch of SPI NOR entries to the flash_info table
- Add the concept of SFDP fixups and use it to fix a bug on MX25L25635F
- A bunch of minor cleanups/comestic changes
NAND core changes:
- kernel-doc miscellaneous fixes.
- Third batch of fixes/cleanup to the raw NAND core impacting various
controller drivers (ams-delta, marvell, fsmc, denali, tegra,
vf610):
* Stop to pass mtd_info objects to internal functions
* Reorganize code to avoid forward declarations
* Drop useless test in nand_legacy_set_defaults()
* Move nand_exec_op() to internal.h
* Add nand_[de]select_target() helpers
* Pass the CS line to be selected in struct nand_operation
* Make ->select_chip() optional when ->exec_op() is implemented
* Deprecate the ->select_chip() hook
* Move the ->exec_op() method to nand_controller_ops
* Move ->setup_data_interface() to nand_controller_ops
* Deprecate the dummy_controller field
* Fix JEDEC detection
* Provide a helper for polling GPIO R/B pin
Raw NAND chip drivers changes:
- Macronix:
* Flag 1.8V AC chips with a broken GET_FEATURES(TIMINGS)
Raw NAND controllers drivers changes:
- Ams-delta:
* Fix the error path
* SPDX tag added
* May be compiled with COMPILE_TEST=y
* Conversion to ->exec_op() interface
* Drop .IOADDR_R/W use
* Use GPIO API for data I/O
- Denali:
* Remove denali_reset_banks()
* Remove ->dev_ready() hook
* Include <linux/bits.h> instead of <linux/bitops.h>
* Changes to comply with the above fixes/cleanup done in the core.
- FSMC:
* Add an SPDX tag to replace the license text
* Make conversion from chip to fsmc consistent
* Fix unchecked return value in fsmc_read_page_hwecc
* Changes to comply with the above fixes/cleanup done in the core.
- Marvell:
* Prevent timeouts on a loaded machine (fix)
* Changes to comply with the above fixes/cleanup done in the core.
- OMAP2:
* Pass the parent of pdev to dma_request_chan() (fix)
- R852:
* Use generic DMA API
- sh_flctl:
* Convert to SPDX identifiers
- Sunxi:
* Write pageprog related opcodes to the right register: WCMD_SET (fix)
- Tegra:
* Stop implementing ->select_chip()
- VF610:
* Add an SPDX tag to replace the license text
* Changes to comply with the above fixes/cleanup done in the core.
- Various trivial/spelling/coding style fixes.
SPI-NAND drivers changes:
- Remove the depreacated mt29f_spinand driver from staging.
- Add support for:
* Toshiba TC58CVG2S0H
* GigaDevice GD5FxGQ4xA
* Winbond W25N01GV
JFFS2 changes:
- Fix a lockdep issue
MTD changes:
- Rework the physmap driver to merge gpio-addr-flash and physmap_of
in it
- Add a new compatible for RedBoot partitions
- Make sub-partitions RW if the parent partition was RO because of a
mis-alignment
- Add pinctrl support to the
- Addition of /* fall-through */ comments where appropriate
- Various minor fixes and cleanups
Other changes:
