Pull MTD updates from Brian Norris:
 "NAND, from Boris:
   - some minor fixes/improvements on existing drivers (fsmc, gpio, ifc,
     davinci, brcmnand, omap)
   - a huge cleanup/rework of the denali driver accompanied with core
     fixes/improvements to simplify the driver code
   - a complete rewrite of the atmel driver to support new DT bindings
     make future evolution easier
   - the addition of per-vendor detection/initialization steps to avoid
     extending the nand_ids table with more extended-id entries

  SPI NOR, from Cyrille:
   - fixes in the hisi, intel and Mediatek SPI controller drivers
   - fixes to some SPI flash memories not supporting the Chip Erase
     command.
   - add support to some new memory parts (Winbond, Macronix, Micron,
     ESMT).
   - add new driver for the STM32 QSPI controller

  And a few fixes for Gemini and Versatile platforms on physmap-of"

mtd: nand: denali_dt: remove dma-mask DT property

2017-04-25T12:18:36+00:00

The driver sets appropriate DMA mask.  Delete the "dma-mask" DT
property.  See [1] for negative comments for this binding.

mtd: nand: denali_dt: enable HW_ECC_FIXUP for Altera SOCFPGA variant

2017-04-25T12:18:34+00:00

There are various customizable parameters, so several variants for
this IP.  A generic compatible like "denali,denali-nand-dt" is
useless.  Moreover, there are multiple things wrong with this string.
(Refer to Rob's comment [1])

The "denali,denali-nand-dt" was added by Altera for the SOCFPGA port.
Replace it with a more specific string "altr,socfpga-denali-nand".
There are no users (in upstream) of the old compatible string.

The Denali IP on SOCFPGA incorporates the hardware ECC fixup engine.
So, this capability should be associated with the compatible.

mtd: nand: atmel: Document the new DT bindings

2017-04-25T12:18:29+00:00

The old NAND bindings were not exactly describing the hardware topology
and were preventing definitions of several NAND chips under the same
NAND controller.

New bindings address these limitations and should be preferred over the
old ones for new SoCs/boards.
Old bindings are still supported for backward compatibility but are
marked deprecated in the doc.
