Merge tag 'juno-updates-4.13' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into next/dt64
ARMv8 Vexpress/Juno DT updates for v4.13
1. Adds support for Coresight CPU debug MMIO interface on all Juno variants.
2. Enables support for few SMMUs on Juno which were previously disabled
waiting for IOMMU-backed DMA API support to be stabilised.
* tag 'juno-updates-4.13' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux:
arm64: dts: juno: enable some SMMUs
arm64: dts: juno: add coresight CPU debug nodes
