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"
