The ACPI 6.1 specification was recently released at the end of January 2016, but the arm64 kernel documentation for the use of ACPI was written for the 5.1 version of the spec. There were significant additions to the spec that had not yet been mentioned -- for example, the 6.0 mechanisms added to make it easier to define processors and low power idle states, as well as the 6.1 addition allowing regular interrupts (not just from GPIO) be used to signal ACPI general purpose events.
This patch reflects going back through and examining the specs in detail and updating content appropriately. Whilst there, a few odds and ends of typos were caught as well. This brings the documentation up to date with ACPI 6.1 for arm64.
Changes for v3: -- Clarify use of _LPI/_RDI (Vikas Sajjan) -- Whitespace cleanup as pointed out by checkpatch
Changes for v2: -- Clean up white space (Harb Abdulhahmid) -- Clarification on _CCA usage (Harb Abdulhamid) -- IORT moved to required from recommended (Hanjun Guo) -- Clarify IORT description (Hanjun Guo)

Ping? Any further comments or is this good to go?
It would be nice to see an ack from some other ACPI people, if that's possible. Which tree were you planning to merge this through?
