driver core: platform_bus: allow runtime override of dev_pm_ops

2010-10-22T17:16:42+00:00

Currently, the platform_bus allows customization of several of the
busses dev_pm_ops methods by using weak symbols so that platform code
can override them.  The weak-symbol approach is not scalable when
wanting to support multiple platforms in a single kernel binary.

Instead, provide __init methods for platform code to customize the
dev_pm_ops methods at runtime.

NOTE: after these dynamic methods are merged, the weak symbols should
      be removed from drivers/base/platform.c.  AFAIK, this will only
      affect SH and sh-mobile which should be converted to use this
      runtime approach instead of the weak symbols.  After SH &
      sh-mobile are converted, the weak symobols could be removed.

Tested on OMAP3.

Driver core: reduce duplicated code for platform_device creation

2010-08-05T20:53:34+00:00

This makes the two similar functions platform_device_register_simple
and platform_device_register_data one line inline functions using a new
generic function platform_device_register_resndata.

platform: Make platform resource input parameters const

2010-05-17T19:37:40+00:00

Make the platform resource input parameters of platform_device_add_resources()
and platform_device_register_simple() const, as the resources are copied and
never modified.

driver core: make platform_device_id table const

The platform ID table is normally const, force that by adding the attribute.

Driver core: add platform_create_bundle() helper

2010-03-08T01:04:46+00:00

Many legacy-style module create singleton platform devices themselves,
along with corresponding platform driver. Instead of replicating error
handling code in all such drivers, provide a helper that allocates and
registers a single platform device and a driver and binds them together.

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.

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: Add platform device arch data V3

2009-07-21T22:28:38+00:00

Allow architecture specific data in struct platform_device V3.

With this patch struct pdev_archdata is added to struct
platform_device, similar to struct dev_archdata in found in
struct device. Useful for architecture code that needs to
keep extra data associated with each platform device.

Struct pdev_archdata is different from dev.platform_data, the
convention is that dev.platform_data points to driver-specific
data. It may or may not be required by the driver. The format
of this depends on driver but is the same across architectures.

The structure pdev_archdata is a place for architecture specific
data. This data is handled by architecture specific code (for
example runtime PM), and since it is architecture specific it
should _never_ be touched by device driver code. Exactly like
struct dev_archdata but for platform devices.

[rjw: This change is for power management mostly and that's why it
 goes through the suspend tree.]

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.
