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.

ahci_platform: convert to module_platform_driver

2012-12-03T10:14:31+00:00

The ahci_platform driver can now use the module_platform_driver() macro.

ahci_platform: enable hotplug unbinding

2012-12-03T10:14:07+00:00

platform_driver_probe() should be used for registering this driver only
if we want to

    "...remove its run-once probe() infrastructure from memory after the
    driver has bound to the device."

However, we may want to leave the probe infrastructure in place in order
to support binding/unbinding a device dynamically. This is useful, for
instance, as a power management mechanism, where a device can be totally
powered down when unbound (whereas with runtime power management,
powering down the SATA core would incur unacceptable loss of
functionality).

Thus, convert this driver to use platform_driver_register().

[libata] PM callbacks should be conditionally compiled on CONFIG_PM_SLEEP

2012-11-16T05:45:37+00:00

This will fix warnings like following when CONFIG_PM_SLEEP is not set:

        warning: 'xxx_suspend' defined but not used [-Wunused-function]
        warning: 'xxx_resume' defined but not used [-Wunused-function]

Because
	SET_SYSTEM_SLEEP_PM_OPS(suspend_fn, resume_fn)

Only references the callbacks on CONFIG_PM_SLEEP (instead of CONFIG_PM).

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.

ata: add platform driver for Calxeda AHCI controller

2012-09-13T05:09:41+00:00

Calxeda highbank SATA phy has intermittent problems bringing up a link
with Gen3 drives. Retrying the phy hard reset can work-around this issue,
but each reset also disables spread spectrum support. The reset function
also needs to reprogram the phy to enable spread spectrum support.

Create a new driver based on ahci_platform to support the Calxeda Highbank
SATA controller.
