Brian Norris 8bf57b0dd4 mtd: plat_nand: use default partition probe
It's harmless to add 'ofpart' (the only different parser supported in
default mtdpart.c) to plat_nand. That let's us kill off one more custom
partition prober listing.

Brian Norris c4a3f13c2a mtd: blktrans: use better error code for unimplemented ioctl()
In commit 5018393625 ("mtd: blktrans: change blktrans_getgeo return
value") we fixed the problem that ioctl(HDIO_GETGEO) might return 0
(success) for mtdblock devices which did not implement the feature and
would leave a blank (zero) result.

But now, let's get the error code right. Other code paths on this ioctl
tend to use -ENOTTY to notify the user that the ioctl() is not supported
for the device, so let's use that instead of -EOPNOTSUPP.

Wenlin Kang 5018393625 mtd: blktrans: change blktrans_getgeo return value
Modify function blktrans_getgeo()'s return value to -EOPNOTSUPP when
dev->tr->getgeo == NULL.

We shouldn't make the return value to 0 when dev->tr->getgeo == NULL,
because the function blktrans_getgeo() has an output value "hd_geometry"
which is usually used by some application, if returns 0 (i.e.,
"success"), it will make some application get the wrong information.

Geert Uytterhoeven f650ce24b3 mtd: Allow compile test of GPIO consumers if !GPIOLIB
The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is
not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer
functionality only, can still be compiled if GPIOLIB is not enabled.

Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where
appropriate.

Baruch Siach 0d17fc3e99 mtd: mxc_nand: fix truncate of unaligned oob copying
Copy to/from oob io area might not be aligned to 4 bytes. When 8 bit ECC is
used, the buffer size is 26. Add memcpy16_{to,from}io, and use them to avoid
truncating the buffer. Prefer memcpy32_{to,from}io when the buffer is properly
aligned for better performance.

Peter Zijlstra ab992dc38f watchdog: Fix merge 'conflict'
Two watchdog changes that came through different trees had a non
conflicting conflict, that is, one changed the semantics of a variable
but no actual code conflict happened. So the merge appeared fine, but
the resulting code did not behave as expected.

Commit 195daf665a ("watchdog: enable the new user interface of the
watchdog mechanism") changes the semantics of watchdog_user_enabled,
which thereafter is only used by the functions introduced by
b3738d2932 ("watchdog: Add watchdog enable/disable all functions").

There further appears to be a distinct lack of serialization between
setting and using watchdog_enabled, so perhaps we should wrap the
{en,dis}able_all() things in watchdog_proc_mutex.

This patch fixes a s2r failure reported by Michal; which I cannot
readily explain. But this does make the code internally consistent
again.

Brian Norris 27c5b17cd1 mtd: nand: add NAND driver "library" for Broadcom STB NAND controller
This core originated in Set-Top Box chips (BCM7xxx) but is used in a
variety of other Broadcom chips, including some BCM63xxx, BCM33xx, and
iProc/Cygnus. It's been used only on ARM and MIPS SoCs, so restrict it
to those architectures.

There are multiple revisions of this core throughout the years, and
almost every version broke register compatibility in some small way, but
with some effort, this driver is able to support v4.0, v5.0, v6.x, v7.0,
and v7.1. It's been tested on v5.0, v6.0, v6.1, v7.0, and v7.1 recently,
so there hopefully are no more lurking inconsistencies.

This patch adds just some library support, on which platform drivers can
be built.

Brian Norris 8947e396a8 Documentation: dt: mtd: replace "nor-jedec" binding with "jedec, spi-nor"
In commit 8ff16cf77c ("Documentation: devicetree: m25p80: add "nor-jedec"
binding"), we added a generic "nor-jedec" binding to catch all
mostly-compatible SPI NOR flash which can be detected via the READ ID
opcode (0x9F). This was discussed and reviewed at the time, however
objections have come up since then as part of this discussion:

  http://lkml.kernel.org/g/20150511224646.GJ32500@ld-irv-0074

It seems the parties involved agree that "jedec,spi-nor" does a better
job of capturing the fact that this is SPI-specific, not just any NOR
flash.

This binding was only merged for v4.1-rc1, so it's still OK to change
the naming.

At the same time, let's move the documentation to a better name.

Next up: stop referring to code (drivers/mtd/devices/m25p80.c) from the
documentation.
