Merge tag 'for-linus-20170713' of git://git.infradead.org/linux-mtd

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"

Representing flash partitions in devicetree
Flash partitions in device tree
===============================
Partitions can be represented by sub-nodes of an mtd device. This can be used
Flash devices can be partitioned into one or more functional ranges (e.g. "boot
code", "nvram", "kernel").
Different devices may be partitioned in a different ways. Some may use a fixed
flash layout set at production time. Some may use on-flash table that describes
the geometry and naming/purpose of each functional region. It is also possible
to see these methods mixed.
To assist system software in locating partitions, we allow describing which
method is used for a given flash device. To describe the method there should be
a subnode of the flash device that is named 'partitions'. It must have a
'compatible' property, which is used to identify the method to use.
We currently only document a binding for fixed layouts.
Fixed Partitions
================
Partitions can be represented by sub-nodes of a flash device. This can be used
on platforms which have strong conventions about which portions of a flash are
used for what purposes, but which don't use an on-flash partition table such
as RedBoot.
The partition table should be a subnode of the mtd node and should be named
The partition table should be a subnode of the flash node and should be named
'partitions'. This node should have the following property:
- compatible : (required) must be "fixed-partitions"
Partitions are then defined in subnodes of the partitions node.
For backwards compatibility partitions as direct subnodes of the mtd device are
For backwards compatibility partitions as direct subnodes of the flash device are
supported. This use is discouraged.
NOTE: also for backwards compatibility, direct subnodes that have a compatible
string are not considered partitions, as they may be used for other bindings.
#address-cells & #size-cells must both be present in the partitions subnode of the
mtd device. There are two valid values for both:
flash device. There are two valid values for both:
<1>: for partitions that require a single 32-bit cell to represent their
size/address (aka the value is below 4 GiB)
<2>: for partitions that require two 32-bit cells to represent their
size/address (aka the value is 4 GiB or greater).
Required properties:
- reg : The partition's offset and size within the mtd bank.
- reg : The partition's offset and size within the flash
Optional properties:
- label : The label / name for this partition. If omitted, the label is taken
