Oh. I hadn't noticed that they had it sufficiently mainlined by now.

I wonder why that happens. Hmm, seems that any AM572x will match: DT_MACHINE_START(DRA74X_DT, "Generic DRA74X (Flattened Device Tree)") while AM571x will match: DT_MACHINE_START(DRA72X_DT, "Generic DRA72X (Flattened Device Tree)") That's in arch/arm/mach-omap2/board-generic.c So doesn't mean anything much and simply means the dtb used contained the right compat string to startup as the right CPU type. > I hope that the case is not that an entire interrupt controller's code > needs to be made ipipe-ready, because that is pretty far out of my league. > However, I will look further into the tps659038. > > I removed the palmas driver in stages (piece by piece across several kernel > builds and test boots), and still wound up with a null dereference, even > when the driver was completely removed from the kernel config. > > For your successful Xenomai 2.6.4 run on the 3.14 kernel, were you using > the ti-linux-kernel, or mainline?
