The idle-states bindings mandate that the entry-method string
in the idle-states node must be "psci" for ARM v8 64-bit systems,
but the examples in the bindings report a wrong entry-method string.
Owing to this typo, some dts in the kernel wrongly defined the
entry-method property, since they likely cut and pasted the example
definition without paying attention to the bindings definitions.

This patch fixes the typo in the DT idle states bindings examples and
respective dts in the kernel so that the bindings and related dts
files are made compliant.

The gpiolib supports parsing DT properties of the form <name>-gpio but it
was only added for compatibility with older DT bindings that got it wrong
and should not be used in newer bindings.

The commit that added support for this was:

dd34c37a ("gpio: of: Allow -gpio suffix for property names")

but didn't update the documentation to explain this so it's been a source
of confusion. So let's make this clear in the GPIO DT binding doc.

The bma180 / bma250 accelerometers share a driver (at least under Linux),
so it makes sense to also have their bindings info in a single .txt.

This commit extends the bma180 bindings with bma250 bindings, specifically
it specifies how the 2 seperate interrupts the bma250 has must be listed
in devicetree. The existing bma180 driver is already fully compatible
with the specified bindings.

supported by the leds-ns2 driver.

With this patch the hardcoded mapping is removed from leds-ns2. Now,
it must be defined either in the platform data (if an old-fashion board
setup file is used) or in the DT node. In order to allow the later, this
patch also introduces a modes-map property for the leds-ns2 DT binding.
