Copying what Arnd was writing on IRC this morning, Eric, Stefan, can you
implement what Arnd recommends and I will pull again or cherry-pick
(whatever you prefer) thanks! Arnd, how quickly should we give you a new
PR with those changes?
10:07 < arnd> [florian], anholt, maz: I looked at the
arm-soc/for-4.14/soc pull request again now, and wonder if we can do a
little better than that
10:08 < arnd> it seems you have pulled in the DT branch before the move
of the bcm2836_smp_ops from drivers/irqchip to arch/arm/mach-bcm, to
hide an incompatible DT binding change: in the old code, no
enable-method was needed, but now it is
10:09 < arnd> clearly we want the enable-method to be there, but it
would be good if old dts files could keep working, in particular as
there are probably lots of people that hack their dts files to add
random peripherals, and we don't want to force them to update their
dtb with every kernel change
10:11 < arnd> how about we add a .smp_init handler to
DT_MACHINE_START(BCM2835, ...) to keep it working with the old DT?
10:12 < arnd> that would also get rid of the branch dependency as an
added bonus, but avoiding the boot breakage is more important of course
10:13 < arnd> Stefan Wahren did the patch, but he's either not on this
channel, or I don't know his nick
10:30 < arnd> on a related note, I see that the match table for the
machine descriptor doesn't list bcm2837, and the bcm2837.dtsi file
doesn't list itself as compatible with bcm2836, so that would have to be
added too to make it actually work
