Robert Richter 2cc1144a31 sata_highbank: Rename proc_name to the module name
mkinitrd looks at /sys/class/scsi_host/host$hostnum/proc_name to find
the module name of a disk driver. Current name is "highbank-ahci" but
the module is "sata_highbank". Rename it to match the module name.

not exported.

Greg Kroah-Hartman 0ec2491467 Drivers: ata: remove __dev* attributes.
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.

Sergei Shtylyov 121650a555 sata_highbank: use ATA_BUSY
ahci_highbank_hardreset() uses bare number for the BSY bit of the ATA status
register, despite it is #define'd in <linux/ata.h>

Yuanhan Liu 29448ec129 [libata] PM callbacks should be conditionally compiled on CONFIG_PM_SLEEP
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).

Arnd Bergmann c37472d3f4 sata_highbank: mark ahci_highbank_probe as __devinit
The ahci_highbank_probe function is incorrectly marked as __init,
which means it can get discarded at boot time, which might be
a problem if for some reason the device only becomes operational
after loading another module.

Using __devinit instead avoids seeing this warning for every build:

WARNING: vmlinux.o(.data+0xf7b0): Section mismatch in reference from the
variable ahci_highbank_driver to the function .init.text:ahci_highbank_probe()
The variable ahci_highbank_driver references
the function __init ahci_highbank_probe()
If the reference is valid then annotate the
variable with __init* or __refdata (see linux/init.h) or name the variable:
*_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console

Mark Langsdorf 8996b89d6b ata: add platform driver for Calxeda AHCI controller
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.
