# HG changeset patch
# User Paul Durrant <paul.durrant@xxxxxxxxxx>
# Date 1321612462 0
# Node ID 3e977aa71278d30aad3d9eb3e5b6413cbcfc0f4e
# Parent 8a29891d6a98002b299d73253935c161ecf393a1
Add configuration options to selectively disable S3 and S4 ACPI power states.
Introduce acpi_s3 and acpi_s4 configuration options (default=1). The S3 and S4
packages are moved into separate SSDTs and their inclusion is controlled by the
new configuration options.
