Pull MTD updates from Boris Brezillon:
"Core MTD changes:
- Use struct_size() where appropriate
- mtd_{read,write}() as wrappers around mtd_{read,write}_oob()
- Fix misuse of PTR_ERR() in docg3
- Coding style improvements in mtdcore.c
SPI NOR changes:
Core changes:
- Add support of octal mode I/O transfer
- Add a bunch of SPI NOR entries to the flash_info table
SPI NOR controller driver changes:
- cadence-quadspi:
* Add support for Octal SPI controller
* write upto 8-bytes data in STIG mode
- mtk-quadspi:
* rename config to a common one
* add SNOR_HWCAPS_READ to spi_nor_hwcaps mask
- Add Tudor as SPI-NOR co-maintainer
NAND changes:
NAND core changes:
- Fourth batch of fixes/cleanup to the raw NAND core impacting
various controller drivers (Sunxi, Marvell, MTK, TMIO, OMAP2).
- Check the return code of nand_reset() and nand_readid_op().
- Remove ->legacy.erase and single_erase().
- Simplify the locking.
- Several implicit fall through annotations.
Raw NAND controllers drivers changes:
- Fix various possible object reference leaks (MTK, JZ4780, Atmel)
- ST:
* Add support for STM32 FMC2 NAND flash controller
- Meson:
* Add support for Amlogic NAND flash controller
- Denali:
* Several cleanup patches
- Sunxi:
* Several cleanup patches
- FSMC:
* Disable NAND on remove()
* Reset NAND timings on resume()
SPI-NAND drivers changes:
- Toshiba:
* Add support for all Toshiba products.
- Macronix:
* Fix ECC status read.
- Gigadevice:
* Add support for GD5F1GQ4UExxG"
* tag 'mtd/for-5.1' of git://git.infradead.org/linux-mtd: (64 commits)
