I tested this patch series (plus the necessary dts changes) on a DRA7xx-EVM with the work in progress VIP driver which needs a crossbar mapping otherwise it won't get any interrupts (using 3.15-rc4 kernel). It boots cleanly and interrupts are firing for VIP, so everything working for me. Without this patch series I can't even get the DRA7xx EVM to boot with IRQ crossbar support enabled so this is a big improvement.
