ata/ahci_platform: Add clock framework support

2012-09-13T05:10:18+00:00

On many architectures, drivers are supposed to prepare/unprepare &
enable/disable functional clock of device. This patch adds clock support for
ahci_platform.

ahci: implement aggressive SATA device sleep support

2012-09-13T05:08:53+00:00

Device Sleep is a feature as described in AHCI 1.3.1 Technical Proposal.
This feature enables an HBA and SATA storage device to enter the DevSleep
interface state, enabling lower power SATA-based systems.

Aggressive Device Sleep enables the HBA to assert the DEVSLP signal as
soon as there are no commands outstanding to the device and the port
specific Device Sleep idle timer has expired. This enables autonomous
entry into the DevSleep interface state without waiting for software
in power sensitive systems.

This patch enables Aggressive Device Sleep only if both host controller
and device support it.

Tested on AMD reference board together with Device Sleep supported device
sample.

ahci: move AHCI_HFLAGS() macro to ahci.h

2012-03-13T20:35:47+00:00

We will need this macro in both ahci.c and ahci_platform.c, so just move it
to the header.

ahci: add AHCI_HFLAG_DELAY_ENGINE host flag

2012-03-13T20:35:37+00:00

The following commit was intended to fix problems with specific AHCI
controller(s) that would become bricks if the AHCI specification was not
followed strictly (that is, if ahci_start_engine() was called while the
controller was in the wrong state):

    commit 7faa33da9b7add01db9f1ad92c6a5d9145e940a7
    ahci: start engine only during soft/hard resets

However, some devices currently have issues with that fix, so we must
implement a flag that delays the ahci_start_engine() call only for specific
controllers.

This commit simply introduces the flag, without enabling it in any driver.

Note that even when AHCI_HFLAG_DELAY_ENGINE is not enabled, this patch does
not constitue a full revert to commit 7faa33da; there is still a change in
behavior to the ahci_port_suspend() failure path.

libata: remove ATA_FLAG_LPM

Commit 6b7ae9545ad9875a289f4191c0216b473e313cb9 (libata: reimplement link power
management) removed the check of ATA_FLAG_LPM but neglected to remove the flag
itself.  Do it now...

libata: remove ATA_FLAG_NO_LEGACY

All checks of ATA_FLAG_NO_LEGACY have been removed by the commits
c791c30670ea61f19eec390124128bf278e854fe ([libata] minor PCI IDE probe
fixes and cleanups) and f0d36efdc624beb3d9e29b9ab9e9537bf0f25d5b (libata:

get rid of this flag...
