PM / Domains: Rename struct dev_power_domain to struct dev_pm_domain

2011-07-02T12:29:54+00:00

The naming convention used by commit 7538e3db6e015e890825fbd9f86599b
(PM: Add support for device power domains), which introduced the
struct dev_power_domain type for representing device power domains,
evidently confuses some developers who tend to think that objects
of this type must correspond to "power domains" as defined by
hardware, which is not the case.  Namely, at the kernel level, a
struct dev_power_domain object can represent arbitrary set of devices
that are mutually dependent power management-wise and need not belong
to one hardware power domain.  To avoid that confusion, rename struct
dev_power_domain to struct dev_pm_domain and rename the related
pointers in struct device and struct pm_clk_notifier_block from
pwr_domain to pm_domain.

sh: cosmetic improvement: use an existing pointer

2011-05-23T03:37:26+00:00

Use an existing local variable, instead of calculating the pointer
multiple times explicitly.

shmobile: Use power domains for platform runtime PM

2011-04-28T22:36:21+00:00

shmobile platforms replace the runtime PM callbacks of the platform
bus type with their own routines, but this means that the callbacks
are replaced system-wide.  This may not be the right approach if the
platform devices on the system are not of the same type (e.g. some
of them belong to an SoC and the others are located in separate
chips), because in those cases they may require different handling.
Thus it is better to use power domains to override the platform bus
type's PM handling, as it generally is possible to use different
power domains for devices with different PM requirements.

Define a default power domain for shmobile in both the SH and ARM
falvors and use it to override the platform bus type's PM callbacks.
Since the suspend and hibernate callbacks of the new "default" power
domains need to be the same and the platform bus type's suspend and
hibernate callbacks for the time being, export those callbacks so
that can be used outside of the platform bus type code.

sh: Rename cpuidle states to fit general conventions

2011-03-11T03:30:12+00:00

C0 is known as "busy", "not idle" state.
X86 "busy polling" state also got renamed from C0
to "POLL" recently.
Let's stay consistent with naming to avoid confusions.

suspend: constify platform_suspend_ops

2010-11-16T13:14:02+00:00

While at it, fix two checkpatch errors.
Several non-const struct instances constified by this patch were added after
the introduction of platform_suspend_ops in checkpatch.pl's list of "should
be const" structs (79404849e90a41ea2109bd0e2f7c7164b0c4ce73).

Patch against mainline.
Inspired by hunks of the grsecurity patch, updated for newer kernels.

sh: allow runtime pm without suspend/resume callbacks

2009-12-04T04:42:37+00:00

This patch updates the Runtime PM code for SuperH Mobile
to allow drivers to have NULL as pm or callback value.
With this in place there is no need for no-op functions.
