Pull MTD updates from Brian Norris:
 "General updates:
   - Cleanups and additional flash support for "dataflash" driver
   - new driver for mchp23k256 SPI SRAM device
   - improve handling of MTDs without eraseblocks (i.e., MTD_NO_ERASE)
   - refactor and improve "sub-partition" handling with TRX partition
     parser; partitions can now be created as sub-partitions of another
     partition

  SPINOR updates, from Cyrille Pitchen and Marek Vasut:
   - introduce support to the SPI 1-2-2 and 1-4-4 protocols.
   - introduce support to the Double Data Rate (DDR) mode.
   - introduce support to the Octo SPI protocols.
   - add support to new memory parts for Spansion, Macronix and Winbond.
   - add fixes for the Aspeed, STM32 and Cadence QSPI controler drivers.
   - clean up the st_spi_fsm driver.

  NAND updates, from Boris Brezillon:
   - addition of on-die ECC support to Micron driver
   - addition of helpers to help drivers choose most appropriate ECC
     settings
   - deletion of dead-code (cached programming and ->errstat() hook)
   - make sure drivers that do not support the SET/GET FEATURES command
     return ENOTSUPP use a dummy ->set/get_features implementation
     returning -ENOTSUPP (required for Micron on-die ECC)
   - change the semantic of ecc->write_page() for drivers setting the
     NAND_ECC_CUSTOM_PAGE_ACCESS flag
   - support exiting 'GET STATUS' command in default ->cmdfunc()
     implementations
   - change the prototype of ->setup_data_interface()

  A bunch of driver related changes:
   - various cleanup, fixes and improvements of the MTK driver
   - OMAP DT bindings fixes
   - support for ->setup_data_interface() in the fsmc driver
   - support for imx7 in the gpmi driver
   - finalization of the denali driver rework (thanks to Masahiro for
     the work he's done on this driver)
   - fix "bitflips in erased pages" handling in the ifc driver
   - addition of PM ops and dynamic timing configuration to the atmel
     driver"
