----------------------------------------------------------------
* MTD changes

No particularly important patchset this cycle, but we have a few usual
improvements: like using a better/more recent helper or checking a
return value.

* Raw NAND changes

The use of for_each_child_of_node_scoped() has been spread into the
subsystem drivers. Aside from that, a couple of exit path have been
fixed (mtk, denali), the TI GPMC bindings have been enhanced to comply
with up-to-date partition descriptions and as always there is a load of
small and misc fixes.

* SPI-NAND changes

The most impacting series this cycle is bringing support for continuous
reads in the SPI-NAND subsystem. This is a feature already merged in the
raw NAND subsystem which allows optimizing the internal fetch times in
the chip while reading sequential pages within an eraseblock. For now
only Macronix NANDs benefit from this feature. While we are talking
about Macronix, some of their chip need an explicit action for selecting
a different plane, and support for it has also been brought.

The bitflip threshold has also been set to the same arbitrary level as
in the raw NAND subsystem to optimize wear leveling decisions, and
finally support for a new Winbond chip has been added.

* SPI NOR changes

Notable changes:
- Add Write Protect support for N25Q064A.
- New flash support for Zetta ZD25Q128C and Spansion S28HS256T.
- Fix a NULL dereference in probe path for flashes without a name. The
  probe path tries to access the name without checking its existence
  first. S28HS256T is the first flash to define its entry without a
  name, uncovering this issue.
