Merge tag 'mtd/for-4.18' of git://git.infradead.org/linux-mtd
Pull MTD updates from Boris Brezillon:
"Core changes:
- Add a sysfs attribute to expose available OOB size
Driver changes:
- Remove HAS_DMA dependency on various drivers
- Use dev_get_drvdata() instead of platform_get_drvdata() in docg3
- Replace msleep by usleep_range() in the dataflash driver
- Avoid VLA usage in nftl layers
- Remove useless .owner assignment in pismo
- Fix various issues in the CFI driver
- Improve TRX partition handling expose a DT compat for this part
parser
- Clarify OFFSET_CONTINUOUS meaning
NAND core changes:
- Add Miquel as a NAND maintainer
- Add access mode to the nand_page_io_req struct
- Fix kernel-doc in rawnand.h
- Support bit-wise majority to recover from corrupted ONFI parameter
pages
- Stop checking FAIL bit after a SET_FEATURES, as documented in the
ONFI spec
Raw NAND Driver changes:
- Fix and cleanup the error path of many NAND controller drivers
- GPMI:
+ Cleanup/simplification of a few aspects in the driver
+ Take ECC setup specified in the DT into account
- sunxi: remove support for GPIO-based R/B polling
- MTK:
+ Use of_device_get_match_data() instead of of_match_device()
+ Add an entry in MAINTAINERS for this driver
+ Fix nand-ecc-step-size and nand-ecc-strength description in the
DT bindings doc
- fsl_ifc: fix ->cmdfunc() to read more than one ONFI parameter page
OneNAND driver changes:
- samsung: use dev_get_drvdata() instead of platform_get_drvdata()
SPI NOR core changes:
- Add support for a bunch of SPI NOR chips
- Clear EAR reg when switching to 3-byte addressing mode on Winbond
chips
SPI NOR controller driver changes:
- cadence: Add DMA support for direct mode reads
- hisi: Prefix a few functions with hisi_
- intel:
+ Mark the driver as "dangerous" in Kconfig
+ Fix atomic sequence handling
+ Pass a 40us delay (instead of 0us) to readl_poll_timeout()
- fsl:
+ fix a typo in a function name
+ add support for IP variants embedded in the ls2080a and ls1080a
SoCs
- stm32: request exclusive control of the reset line"
