Subject: [PATCH v1 1/4] ide: use generic power management
Earlier, drivers had to manage the device's power states, and related
operations, themselves. With the generic approach, these are done by PCI
core.
The ide_pci_suspend() and ide_pci_resume(), declared in
include/linux/ide.h and defined in drivers/ide/setup-pci.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/ide.h and define
it in drivers/ide/setup-pci.c with SIMPLE_DEV_PM_OPS macro, binding
suspend, and resume callbacks with it. This object can now be used by other
source files.
The following source files are binding same dev_pm_ops object in their PM:
drivers/ide/aec62xx.c
drivers/ide/alim15x3.c
drivers/ide/amd74xx.c
drivers/ide/atiixp.c
drivers/ide/cmd64x.c
drivers/ide/cs5520.c
drivers/ide/cs5530.c
drivers/ide/cs5535.c
drivers/ide/cs5536.c
drivers/ide/cy82c693.c
drivers/ide/hpt366.c
drivers/ide/ide-pci-generic.c
drivers/ide/it8172.c
drivers/ide/it8213.c
drivers/ide/it821x.c
drivers/ide/jmicron.c
drivers/ide/ns87415.c
drivers/ide/opti621.c
drivers/ide/pdc202xx_new.c
drivers/ide/pdc202xx_old.c
drivers/ide/piix.c
drivers/ide/serverworks.c
drivers/ide/setup-pci.c
drivers/ide/siimage.c
drivers/ide/sis5513.c
drivers/ide/sl82c105.c
drivers/ide/slc90e66.c
drivers/ide/via82cxxx.c
include/linux/ide.h
The drivers/ide/triflex.c driver was also using ide_pci_resume() callback
but it had its own definition for .suspend() as it does not want to power
off the device during suspend. Hence, it was excluded from generic pm
upgrade and was provided a static triflex_ide_pci_resume() with definition
same as of ide_pci_resume() to prevent it from breaking. A PCI quirk is
needed while upgrading it for generic PM support.
Compile-tested only.
