It is a Bad Idea (TM) to call mtd_device_register() or
mtd_device_parse_register() twice on the same master MTD. Among other
things, it makes partition overrides (e.g., cmdlinepart) much more
difficult.
Since commit 727dc612c4 ("mtd: part: Create the master device node
when partitioned"), we now have a config option that accomplishes the
same purpose as the double-registration done in diskonchip.c -- it
forces the master MTD to *always* be registered, while partitions may
optionally show up in addition. Eventually, we might like to make
CONFIG_MTD_PARTITIONED_MASTER into the default, but this could be
disruptive to user-space expectations of MTD numbering, so we'll take
that slowly.

(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.

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.

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.

for the samsung platforms
- updates to the files that belong to Marvell mvebu
Bug fixes:
- The largest changes are on omap2, but are only to avoid some
harmless warnings and to fix reset on omap4
- a small regression fix on tegra
- multiple fixes for incorrect IRQ affinity on vexpress
- the missing system controller on arm64 juno is added
- one revert of a patch that was accidentally applied
twice for mach-rockchip

"Specifics:
- fix an issue in intel_powerclamp driver that idle injection target
is not accurately maintained on newer Intel CPUs. Package C8 to
C10 states are introduced on these CPUs but they were not included
in the package c-state residency calculation. From Jacob Pan.
- fix a problem that package c-state idle injection was missing on
Broadwell server, by adding its id to intel_powerclamp driver.
From Jacob Pan.
- a couple of small fixes and cleanups from Joe Perches, Mathias
Krause, Dan Carpenter and Anand Moon"

There are a few small hooks required for chips like BCM63138 and the
iProc family. Let's introduce those now.

Add notes to describe how some SoCs integrate this NAND core a little
differently, and so we define extra compatibility strings and register
resources/names.

BCM7xxx chips are supported entirely by the library code, since they use
generic irqchip interfaces and don't need any extra SoC-specific
configuration.
Signed-off-by: Brian Norris <computersforpeace@gmail.com>
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.
