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.
