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" * tag 'mtd/for-4.18' of git://git.infradead.org/linux-mtd: (66 commits) mtd: nand: Pass mode information to nand_page_io_req mtd: cfi_cmdset_0002: Change erase one block to enable XIP once mtd: cfi_cmdset_0002: Change erase functions to check chip good only mtd: cfi_cmdset_0002: Change erase functions to retry for error mtd: cfi_cmdset_0002: Change definition naming to retry write operation mtd: cfi_cmdset_0002: Change write buffer to check correct value mtd: cmdlinepart: Update comment for introduction of OFFSET_CONTINUOUS mtd: bcm47xxpart: add of_match_table with a new DT binding dt-bindings: mtd: document Broadcom's BCM47xx partitions mtd: spi-nor: Add support for EN25QH32 mtd: spi-nor: Add support for is25wp series chips mtd: spi-nor: Add Winbond w25q32jv support mtd: spi-nor: fsl-quadspi: add support for ls2080a/ls1080a mtd: spi-nor: stm32-quadspi: explicitly request exclusive reset control mtd: spi-nor: intel: provide a range for poll_timout mtd: spi-nor: fsl-quadspi: fix api naming typo _init_ahb_read mtd: spi-nor: intel-spi: Explicitly mark the driver as dangerous in Kconfig mtd: spi-nor: intel-spi: Fix atomic sequence handling mtd: rawnand: Do not check FAIL bit when executing a SET_FEATURES op mtd: rawnand: use bit-wise majority to recover the ONFI param page ...
