Driver core: allow certain drivers prohibit bind/unbind via sysfs

2009-10-30T21:59:51+00:00

Platform drivers registered via platform_driver_probe() can be bound
to devices only once, upon registration, because discard their probe()
routines to save memory. Unbinding the driver through sysfs 'unbind'
leaves the device stranded and confuses users so let's not create
bind and unbind attributes for such drivers.

PM: Run-time PM platform device bus support

2009-08-22T22:05:31+00:00

This patch adds default Runtime PM callbacks to the dev_pm_ops
belonging to the platform bus. The callbacks are weak symbols
that architecture specific code can override.

Allows Runtime PM even though CONFIG_PM_SLEEP=n.

PM / Driver Core: Kill dev_pm_ops platform warning for now

2009-08-10T21:41:18+00:00

Commit 783ea7d4eeefe895f2731fe73ac951e94418927b
(Driver Core: Rework platform suspend/resume, print warning)
added a warning message printed for platform drivers that use the
legacy PM callbacks rather than struct dev_pm_ops.  Unfortunately,
this resulted in some confusion and made some people try to convert
drivers by replacing the old callbacks with struct dev_pm_ops in
automatic way, which generally is not a good idea.

Remove the platform device runtime dev_pm_ops warning for now,
because it's annoying to users and it's not really necessary right
now.

[rjw: Modified the changelog to be more informative.]

Driver Core: Make PM operations a const pointer

They are not supposed to be modified by drivers, so make them const.

PM: Remove platform device suspend_late()/resume_early() V2

2009-07-21T22:28:39+00:00

This is V2 of the platform driver power management late/early
callback removal patch. The callbacks ->suspend_late() and
->resume_early() are removed since all in-tree users now have
been migrated to dev_pm_ops.

driver core: Const-correct platform getbyname functions

2009-06-16T04:30:24+00:00

This converts resource and IRQ getbyname functions for the platform
bus to use const char *, I ran into compiler moanings when I tried
using a const char * for looking up a certain resource.

Driver Core: Rework platform suspend/resume, print warning

2009-06-12T19:32:32+00:00

This patch reworks the platform driver code for legacy
suspend and resume to avoid installing callbacks in
struct device_driver. A warning is also added telling
users to update the platform driver to use dev_pm_ops.

The functions platform_legacy_suspend()/resume() directly
call suspend and resume callbacks in struct platform_driver
instead of wrapping things in platform_drv_suspend()/resume().
