Merge tag 'mtd/for-4.17' of git://git.infradead.org/linux-mtd

Pull MTD updates from Boris Brezillon: "MTD Core: - Remove support for asynchronous erase (not implemented by any of the existing drivers anyway) - Remove Cyrille from the list of SPI NOR and MTD maintainers - Fix kernel doc headers - Allow users to define the partitions parsers they want to test through a DT property (compatible of the partitions subnode) - Remove the bfin-async-flash driver (the only architecture using it has been removed) - Fix pagetest test - Add extra checks in mtd_erase() - Simplify the MTD partition creation logic and get rid of mtd_add_device_partitions() MTD Drivers: - Add endianness information to the physmap DT binding - Add Eon EN29LV400A IDs to JEDEC probe logic - Use %*ph where appropriate SPI NOR Drivers: - Make fsl-quaspi assign different names to MTD devices connected to the same QSPI controller - Remove an unneeded driver.bus assigned in the fsl-qspi driver NAND Core: - Prepare arrival of the SPI NAND subsystem by implementing a generic (interface-agnostic) layer to ease manipulation of NAND devices - Move onenand code base to the drivers/mtd/nand/ dir - Rework timing mode selection - Provide a generic way for NAND chip drivers to flag a specific GET/SET FEATURE operation as supported/unsupported - Stop embedding ONFI/JEDEC param page in nand_chip NAND Drivers: - Rework/cleanup of the mxc driver - Various cleanups in the vf610 driver - Migrate the fsmc and vf610 to ->exec_op() - Get rid of the pxa driver (replaced by marvell_nand) - Support ->setup_data_interface() in the GPMI driver - Fix probe error path in several drivers - Remove support for unused hw_syndrome mode in sunxi_nand - Various minor improvements" * tag 'mtd/for-4.17' of git://git.infradead.org/linux-mtd: (89 commits) dt-bindings: fsl-quadspi: Add the example of two SPI NOR mtd: fsl-quadspi: Distinguish the mtd device names mtd: nand: Fix some function description mismatches in core.c mtd: fsl-quadspi: Remove unneeded driver.bus assignment mtd: rawnand: marvell: Rename ->ecc_clk into ->core_clk mtd: rawnand: s3c2410: enhance the probe function error path mtd: rawnand: tango: fix probe function error path mtd: rawnand: sh_flctl: fix the probe function error path mtd: rawnand: omap2: fix the probe function error path mtd: rawnand: mxc: fix probe function error path mtd: rawnand: denali: fix probe function error path mtd: rawnand: davinci: fix probe function error path mtd: rawnand: cafe: fix probe function error path mtd: rawnand: brcmnand: fix probe function error path mtd: rawnand: sunxi: Stop supporting ECC_HW_SYNDROME mode mtd: rawnand: marvell: Fix clock resource by adding a register clock mtd: ftl: Use DIV_ROUND_UP() mtd: Fix some function description mismatches in mtdcore.c mtd: physmap_of: update struct map_info's swap as per map requirement dt-bindings: mtd-physmap: Add endianness supports ...
