cd3967bee0 soc: ixp4xx: npe: Fix an IS_ERR() vs NULL check in probe
The devm_ioremap_resource() function doesn't return NULL, it returns
error pointers.

Fixes: 0b458d7b10 ("soc: ixp4xx: npe: Pass addresses as resources")

e00797f2e0 soc: ixp4xx: npe: Add DT probe code
This makes the NPE driver able to probe from the device tree.
It only needs to get three memory resources and the plaform
device provide these, so all is pretty simple.

0b458d7b10 soc: ixp4xx: npe: Pass addresses as resources
Instead of using hardcoded base addresses implicitly
obtained through <linux/io.h>, pass the physical base
for the three NPE blocks as memory resources and remap
these in the driver.

Drop the memory request region business, this will
anyways be done by devm_* remapping functions.

bc4d7eafb7 ARM: ixp4xx: Turn the NPE into a platform device
Instead of registering everything related to the NPE
unconditionally in the module_init() call (which will
never work with multiplatform) create a platform device
and probe the NPE like any other device.

Put the device first in the list of devices added for
the platform so it is there when the dependent network
and crypto drivers probe later on.

This probe() path will not be taken unconditionally on
device tree boots, so remove the DT guard.

4af20dc583 ARM: ixp4xx: Move IXP4xx QMGR and NPE headers
This moves the IXP4xx Queue Manager and Network Processing
Engine headers out of the <mack/*> include path as that is
incompatible with multiplatform.

fcf2d8978c ARM: ixp4xx: Move NPE and QMGR to drivers/soc
The Network Processing Engine and Queue Manager are
versatile firmware components used by several IXP4xx
drivers.

Drivers are relying on getting access to these components
using <mach/*> headers which does not work with
multiplatform. We need to find a better place for the
drivers to live.

Let's first move them to drivers/soc and the start to
refactor a bit by passing resources and moving headers.

This patch introduce static IRQ assignments but that
will be fixed by later patches in this series.
