Hi ARM-SoC guys,
Here are couple of fixes for adding missing nodes(CCI and A7 PMUs) in
TC2 device tree. The third patch is addition of support for FPGA based
dual core A53 SMM platform. All the patches are posted on the list
already, just putting them together. Let me know if you prefer a pull
request.
Regards,
Sudeep

Now that we have a mechanism for describing disparate PMUs and their interrupts in device tree, this patch makes use of these to describe the PMUs for all CPUs in the system. For consistency, the existing A15 PMU interrupt-affinity property is reflowed across two lines.

We did discuss this internally with 2 options: 1. Specifying the relative path as done in this patch 2. Creating symlink, something like how kvm manages files today I agree both are not elegant but (1) was chosen to be better of the two. We are open for any suggestions.

Some path for DTSI files which are not specific to a particular architecture, picked up by dtc by default (via -I in default flags)? 4. DTC_FLAGS += -I../../../../arm/boot/dts in arch/arm64/boot/dts/Makefile and using #include "vexpress....dtsi", with the split repo using a different -I in its build system (essentially codifying the relationship between arm64 and arm in the build system instead of the code). IMHO 4 is better than 1 or 3, although still not great. Not sure about 2 myself (from the PoV of working in both contexts).

This just came too late for the v4.2 cycle. I think the first two patches we can take as fixes for v4.2, but the 3rd one will likely need to wait for v4.3.
