Subject: [RFC] ACPI D3Cold state and SATA ZPODD support
Date: Mon, 13 Feb 2012 17:11:05 +0800 [thread overview]
Message-ID: <1329124271-29464-1-git-send-email-ming.m.lin@intel.com> (raw)
Hi all,
This patchset adds support for ACPI D3Cold state and ZPODD(Zero Power
Optical Disk Drive).
ZPODD is a new feature in SATA 3.1 specification. It provides a way to
power off unused CDROM.
CDROM is powered on/off by executing ACPI power resource's _ON/_OFF
method. It enters ACPI D3Cold state when powered off.
PATCH 1 to 4: Adds ACPI D3Cold state support
PATCH 5 to 6: Adds ZPODD support
Applied on top of libata/ALL branch.
[PATCH 1/6] ACPI: Introduce ACPI D3_COLD state support
[PATCH 2/6] ACPI: Reference devices in ACPI Power Resource
[PATCH 3/6] ACPI: Runtime resume all devices covered by a power resource
[PATCH 4/6] PM / Runtime: Introduce flag can_power_off
[PATCH 5/6] PCI: Move acpi_dev_run_wake to acpi core
[PATCH 6/6] libata: add ZPODD support
