Driver core: export platform_device_register_data as a GPL symbol

2009-12-23T19:23:44+00:00

This allows MFD's to register/bind drivers for their sub devices while
still being compiled as a module.

Driver Core: Early platform driver buffer

2009-12-11T19:24:55+00:00

Add early_platform_init_buffer() support and update the
early platform driver code to allow passing parameters
to the driver on the kernel command line.

early_platform_init_buffer() simply allows early platform
drivers to provide a pointer and length to a memory area
where the remaining part of the kernel command line option
will be stored.

Needed to pass baud rate and other serial port options
to the reworked early serial console code on SuperH.

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.

driver core: platform_device_add_data(): use kmemdup()

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.]

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: fix gcc 4.3.3 warnings about string literals

2009-06-16T04:30:25+00:00

This removes the
	warning: format not a string literal and no format arguments
warnings in the driver core that gcc 4.3.3 complains about.
