[ARM] pxa: Fix PXA27x suspend type validation, remove pxa_pm_prepare()

2007-07-12T13:28:06+00:00

pxa_pm_prepare() tried to validate the suspend method type.  As
noted in previous commits:
	eb9289eb20df6b54214c45ac7c6bf5179a149026
	9c372d06ce9ddf65e1393f9ea22a6d6bd5f96b42
	e8c9c502690efd24b7055bf608e7a3c34216848b

the checking of the suspend type in the 'prepare' method is the
wrong place to do this; use the 'valid' method instead.  This
means that pxa_pm_prepare() can be entirely removed.

[ARM] pxa: remove useless pxa_pm_finish() function

2007-07-12T13:27:53+00:00

pxa_pm_finish() does nothing but return zero.  The core code
does nothing with this return value, and will not try to call
the finish method in the pm_ops structure if it is NULL.

Therefore, we can remove this useless function.

PM: do not use saved_state from struct dev_pm_info on ARM

2007-07-11T23:09:02+00:00

The saved_state member of 'struct dev_pm_info' that's going to be removed
is used in arch/arm/common/locomo.c, arch/arm/common/sa1111.c and
arch/arm/mach-sa1100/neponset.c.  Change the code in there to use local
variables for saving the state of devices during suspend.

[ARM] gic: Fix gic cascade irq handling

2007-05-17T09:11:34+00:00

No need for the cascade irq function to have a "fastcall" annotation.
Fix the range checking for valid IRQ numbers - comparing the value
returned by the GIC with NR_IRQS is meaningless since we translate
the GIC irq number to a Linux IRQ number afterwards.

Check the GIC returned IRQ number is within limits first, then add
the IRQ offset, and only then compare with NR_IRQS.

[ARM] 4375/1: sharpsl_pm: Fix compile warnings

Fix compile warnings from sharpsl_pm.c. Attribute registration failure
doesn't stop the driver working so just warn about it.

power management: implement pm_ops.valid for everybody

2007-04-30T23:40:40+00:00

Almost all users of pm_ops only support mem sleep, don't check in .valid and
don't reject any others in .prepare so users can be confused if they check
/sys/power/state, especially when new states are added (these would then
result in s-t-r although they're supposed to be something different).

This patch implements a generic pm_valid_only_mem function that is then
exported for users and puts it to use in almost all existing pm_ops.

rework pm_ops pm_disk_mode, kill misuse

2007-04-30T23:40:40+00:00

This patch series cleans up some misconceptions about pm_ops.  Some users of
the pm_ops structure attempt to use it to stop the user from entering suspend
to disk, this, however, is not possible since the user can always use
"shutdown" in /sys/power/disk and then the pm_ops are never invoked.  Also,
platforms that don't support suspend to disk simply should not allow
configuring SOFTWARE_SUSPEND (read the help text on it, it only selects
suspend to disk and nothing else, all the other stuff depends on PM).

The pm_ops structure is actually intended to provide a way to enter
platform-defined sleep states (currently supported states are "standby" and
"mem" (suspend to ram)) and additionally (if SOFTWARE_SUSPEND is configured)
allows a platform to support a platform specific way to enter low-power mode
once everything has been saved to disk.  This is currently only used by ACPI
(S4).

This patch:

The pm_ops.pm_disk_mode is used in totally bogus ways since nobody really
seems to understand what it actually does.

This patch clarifies the pm_disk_mode description.

It also removes all the arm and sh users that think they can veto suspend to
disk via pm_ops; not so since the user can always do echo shutdown >
/sys/power/disk, they need to find a better way involving Kconfig or such.

ACPI is the only user left with a non-zero pm_disk_mode.

The patch also sets the default mode to shutdown again, but when a new pm_ops
is registered its pm_disk_mode is selected as default, that way the default
stays for ACPI where it is apparently required.
