[PATCH 0/6] Integrator devicetree support

This is a patch set for devicetree on the Integrator/AP and
Integrator/CP I've been cooking. I did some stepwise development
in recent kernels moving to sparse IRQs, per-system clock
source then common clk. Now we can do single zImage and
also devicetree on this platform, so this is a first patch
set.
In case you're wondering why, take down your Torvalds
autobiography and read the title. It was also a bit of
learning exercise, plus it's fun to run devicetree on this
ARMv4 system.
This patch set moves all the non-DT platform code into
#ifndef CONFIG_OF sections for clarity. The plan is to
delete them after deprecation.
Remaining roadblocks to deleting non-DT code altogether.
- Uncertain about how to do the fpga-irq DT binding so
please review closely.
- The Integrator/AP ARM core tiles have add-on logic modules
called Integrator/IM-PD1 with a load of PrimeCells and
stuff. These spawn off a special bus called "lm" in
arch/arm/mach-integrator/lm.c, and the core module support
is in impd1.c. It'd probably be pretty easy to create
device tree bindings for these, but I have no such module
and no clue on where to get one. Is anyone actually using
it? Russell?
- The special PCI adapter in the Integrator has to be DT:ed,
but AFAICT there is still a problem with how to represent
these things in DT. Any hints/examples, Arnd, Rob?
