This is a resend only: Ping? Last ping was 26 May; there has been zero
response since then. Already have one ACK from Lorenzo; another from an
arm64 maintainer would be really helpful.
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 v5:
-- Miscellaneous typos and corrections (Lorenzo Pieralisi)
-- Add linux-acpi@ ML to the distribution list (Alexey Klimov)
-- Corrections to CPPC information (Alexey Klimov)
-- ACK from Lorenzo Pieralisi
-- Updated bibliographic info (Al Stone)
Changes for v4:
-- Clarify that IORT can sometimes be optional (Jon Masters).
-- Remove "Use as needed" descriptions of ACPI objects; they provide
no substantive information and doing so simplifies maintenance of
this document over time. These have been replaced with a simpler
notice that states that unless otherwise noted, do what the ACPI
specification says is needed.
-- Corrected the _OSI object usage recommendation; it described kernel
behavior that does not exist (Al Stone).
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)
