The sign-file.c program actually uses CMS rather than PKCS#7 to sign a file
since that allows the target X.509 certificate to be specified by
subjectKeyId rather than by issuer + serialNumber.
However, older versions of the OpenSSL crypto library (such as may be found
in CentOS 5.11) don't support CMS. Assume everything prior to
OpenSSL-1.0.0 doesn't support CMS and switch to using PKCS#7 in that case.
Further, the pre-1.0.0 OpenSSL only supports PKCS#7 signing with SHA1, so
give an error from the sign-file script if the caller requests anything
other than SHA1.
The compiler gives the following error with an OpenSSL crypto library
that's too old:
HOSTCC scripts/sign-file
scripts/sign-file.c:23:25: fatal error: openssl/cms.h: No such file or directory

- Fix typo in ARM idle-states binding doc and dts files
- Various minor binding documentation updates
* tag 'devicetree-fixes-for-4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux:
Documentation: arm: Fix typo in the idle-states bindings examples
gpio: mention in DT binding doc that <name>-gpio is deprecated

of: thermal: Fix inconsitency between cooling-*-state and cooling-*-level
Docs: dt: add #msi-cells to GICv3 ITS binding
of: add vendor prefix for Socionext Inc.
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:
dd34c37aa3 ("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.

it specifies how the 2 seperate interrupts the bma250 has must be listed
