Rob Herring 791d3ef2e1 dt-bindings: remove 'interrupt-parent' from bindings
'interrupt-parent' is often documented as part of define bindings, but
it is really outside the scope of a device binding. It's never required
in a given node as it is often inherited from a parent node. Or it can
be implicit if a parent node is an 'interrupt-controller' node. So
remove it from all the binding files.

Rob Herring 4da722ca19 dt-bindings: Remove "status" from examples
Pretty much any node can have a status property, so it doesn't need to
be in examples.

Converted with the following command and removed examples with SoC and
board specific splits:

git grep -l -E 'status.*=.*' Documentation/devicetree/ | xargs sed -i -E '/\sstatus.*=.*"(disabled|ok|okay)/d'

Sebastian Reichel 633f67a51d HSI: nokia-modem: add n950 and n9 support
The Nokia N950 and Nokia N9 also have a SSI connected
modem, which use the same protocols as the Nokia N900,
but with increased link speed (96000 kbps instead of
55000 kbps) and with less GPIOs.

Since it's unclear, if the N950 and the N9 use exactly
the same modem, each of them gets their own compatible
string.

Sebastian Reichel eafaebd987 HSI: Introduce Nokia N900 modem driver
The Nokia N900's modem is connected via Synchronous Serial Interface (SSI),
which is a legacy version of MIPI's High-speed Synchronous Serial Interface
(HSI).

The handles the GPIOs for enabling and resetting the modem and instanciates
ssi-protocol for data exchange. It does not yet support exchanging voice data
with the modem.
