ahci: add support for IBM Akebono platform device

2013-11-22T22:38:18+00:00

The new IBM Akebono board has a PPC476GTR SoC with an AHCI compliant
SATA controller. This patch adds a compatible property for the new SoC
to the AHCI platform driver.

Merge branch 'for-3.13' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata

2013-11-13T06:18:22+00:00

Pull libata changes from Tejun Heo:
 "Nothing too interesting.  Only two minor fixes in libata core.  Most
  changes are specific to hardware which isn't too common"

* 'for-3.13' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata:
  ahci: Add Device IDs for Intel Wildcat Point-LP
  sata_rcar: Convert to clk_prepare/unprepare
  drivers/libata: Set max sector to 65535 for Slimtype DVD A DS8A9SH drive
  libata: Add some missing command descriptions
  sata_highbank: clear whole array in highbank_initialize_phys()
  ahci: disabled FBS prior to issuing software reset
  libata: Fix display of sata speed
  ahci: imx: setup power saving methods
  ata_piix: minor typo and a printk fix
  ahci: Changing two module params with static and __read_mostly

ahci: imx: setup power saving methods

2013-10-15T12:47:00+00:00

In order to save power consumption as much as possible.

* Disable sata phy internal pll reference clock when sysetem enter
  into suspend mode, enable it after resume.

* Setup module parameter used to enable imx ahci test power down
  mode(PDDQ) or not, when there is no device detected on the port

* minor modifications:
  - The format of the copyright is changed, because that the original
    one can't pass fsl internal patch reivew without the character
    '(c)'.
  - Exports ahci_platform_ops and ahci_error_handler().

NOTE:
* The hot-plug can't be supported when PDDQ mode is ever enabled.

* module parameter usage how-to:
  - default: enable PDDQ mode when no device detected.
  - add "ahci-imx.hotplug=1" into kernel command line if your don't
    want to enable PDDQ mode when no device detected on the port.

tj: Slightly updated description and comments.

ahci_platform: use dev_info() instead of printk()

2013-10-07T19:17:39+00:00

Change "raw" printk() call to dev_info() to provide a better
message to userspace so it can properly identify the device
and not just have to guess.

ahci: sata: add support for exynos5440 sata

2013-06-17T18:23:05+00:00

This patch adds the compatible string of the exynos5440 sata controller
compliant with the ahci 1.3 and sata 3.0 specification.

changes in v2:
		changed the compatible string by adding the actual IP
owners name instead of the SoC vendor name.

Drivers: ata: remove __dev* attributes.

2013-01-03T23:57:03+00:00

CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

ahci_platform: make structs static

2012-12-14T14:38:17+00:00

These structs are used only for ahci_platform.c, so they should be
static. Thanks to Fengguang for the (automated) suggestion.

ahci_platform: perform platform exit in host_stop() hook

2012-12-03T10:15:15+00:00

AHCI platform devices may provide an exit() routine, via
ahci_platform_data, that powers off the SATA core. Such a routine should
be executed from the ata_port_operations host_stop() hook. That way, the
ATA subsystem can perform any last-minute hardware cleanup (via devres,
for example), then trigger the power-off at the appropriate time.

This patch fixes bus errors triggered during module removal or device
unbinding, seen on an SoC SATA core.
