Subject: [PATCH v2] ata: use generic power management
use generic power management
Drivers using legacy power management .suspen()/.resume() callbacks
have to manage PCI states and device's PM states themselves. They also
need to take care of standard configuration registers.
Switch to generic power management framework using a single
"struct dev_pm_ops" variable to take the unnecessary load from the driver.
This also avoids the need for the driver to directly call most of the PCI
helper functions and device power state control functions, as through
the generic framework PCI Core takes care of the necessary operations,
and drivers are required to do only device-specific jobs.
The ata_pci_device_suspend() and ata_pci_device_resume(), declared in
include/linux/libata.h and defined in drivers/ata/libata-core.c, were
external and were exported. Those were then used by other source files.
Now, as they have to bind with dev_pm_ops object, there is no need to
export them and they can be made static.
Declare an extern const dev_pm_ops object in include/linux/ata.h and define
it in drivers/ata/libata-core.c with SIMPLE_DEV_PM_OPS macro, binding
suspend, and resume callbacks with it. This object can now be used by other
source files.
Now ata_pci_device_suspend() invokes ata_host_suspend(...,pm_message_t).
Earlier, PCI core used to send "PMSG_SUSPEND" argument to pm_message_t
variable of .suspend() which was then passed to .host_suspend(). Since, the
structure of .suspend() has changed, PCI core no more, pass this argument.
Hence, modfy each instance of call to .host_susped(), in respective PCI
drivers, and pass the value "PMSG_SUSPEND" to it.
